Our comparison is between the fuse box of the house and the nucleus. The nucleus of a cell has three parts; nucleus envelope, nucleolus and the nucleus. The nucleolus is inside the nucleus and the nuclear envelope surrounds everything. The nucleolus is filled with jelly like substance, called nucleoplasm. The nucleus is like the “brain” of the cell, and the fuse box is like the ‘brain” of the house. They both have the same thing in common because they both control if we didn’t have a nucleus in the cell, it would not be able to function, and if we didn’t have a fuse box in the house it a lot of things would not operate.
Our comparison is between the mitochondria and the power lines that give energy to the house. The mitochondria’s energy is stored in two types of molecules carbohydrates and lipids. Carbohydrates have fast energy and lipids have long term energy. They both have the same thing in common because they both put out power. If we didn’t have mitochondria, the cells would not have power. If we didn’t have power lines the house would be powerless and nothing would work.
Our comparison is between the ribosome and power outlets in the house. The ribosome of a cell has four types of macromolecules. Those four types are carbohydrates, lipids, nucleic acids, and proteins. The protein is vital to cell function because proteins do pretty much everything. Some of the things they do are signaling, structure, communication, transport movement. So our analogy is good because they both are there to do whatever needs to be done. The power outlets let anything that’s plugged into them work, and the ribosome does almost everything the cell needs.
Our comparison is between the endoplasmic reticulum and an oven in the house. The ER i...

...n into nucleotides. The interior of a lysosome is very acidic. The acid helps to break things down; the acid is very toxic to rest of the cell. Catabolism is breaking things down into smaller parts; anabolism is building molecules out of smaller parts. Catabolism + anabolism= metabolism. Metabolism is the rate at which fuel is broken down and rebuilt into usable molecules.
I’m comparing cilia to a ceiling fan in a house. Cilia are hair –like projections of a cell membrane. The hair-like projections make the cell look furry. The functions of the cilia are to wave in unison to move stuff outside of cell. The cilia increases surface area of a cell and are common in multi cellular organisms. I compared cilia to a fan because they both move stuff. The fan moves air in a house with circular motions. The cilia moves stuff outside the cell with its hair like projections.
The building of the grocery store is like the cell membrane, because it gives it structure and keeps everything inside safe. The security guard of the front door in the grocery store is like the cell membrane, because it says what can come in and out of the cell. The boss of the store is like the nucleus, because they tell the employes what to do and what needs to be done. The floors of the grocery store is like the cytoplasm, because it hold everything in it place, where it need to be. The illes in the store is
Lysosomes contain hydrolytic enzymes which function in the acid of the lysosome and are meant to be secreted not as wastes into the extracellular fluids, but as secretory proteins into an intracellular organelle. When one of these enzymes is dysfunctional, the catabolism of its macromolecule does not completely occur and there is a buildup of the macromolecule inside the lysosome. This results in great numbers of large lysosomes which begin to interfere with the normal functions of the cell. This disorder is called lysosomal storage disorder. These disorders can eventually lead to the dysfunction of the organs. The organs affected by the disorder are determined by two factors: 1) The location in the body where the macromolecules that are to be catabolized are found, and 2) The location where the catabolism occurs.
Animal metabolism consists of the utilization of nutrients absorbed from the digestive tract and their catabolism as fuel for energy or their conversion into substances of the body. Metabolism is a continuous process because the molecules and even most cells of the body have brief lifetimes and are constantly replaced, while tissue as a whole maintains its characteristic structure. This constant rebuilding process without a net change in the amount of a cell constituent is known as dynamic equilibrium (Grolier1996). In the combustion of food, oxygen is used and carbon dioxide is given off. The rate of oxygen consumption indicates the energy expenditure of an organism, or its metabolic rate (Grolier1996).
Enzymes are biomolecules that catalyze or assist chemical reactions. ("Enzyme Information - Disabled World", n.d.,) Without enzymes it would be impossible for an organism to carry out chemical reactions. Enzymes are proteins that carry a chemical reaction for a specific substance or nutrient. For example, the digestive enzymes help food to be broken down so it can be absorbed. Enzymes can either initiate the reaction or speed it up. Substrates are the chemicals that are transformed by enzymes. (Gunsch & Foster, 2014) Reactants are the chemicals in the absence of enzymes. Metabolic pathways that occur in a cell are determined by a set of enzymes which are selective for their substrates and catalyze only a few reactions among the many possibilities.
In contrast, eukaryotic organisms typically include (but are not limited to) membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum (E.R.), golgi body, lysosome and peroxisome. The main defining difference between a eukaryote and prokaryote is that the latter does not contain a nucleus or any such organelles. Such a definition, however, can be argued to be a poor discriminator between organisms of Eukarya and Prokarya, because it describes only what prokaryotes are lacking, not what they fundamentally are. This essay aims to detail a more comprehensive definition of why these two kingdoms are so different from each other. A key example of this thinking is that, while prokaryotes are often singly responsible for metabolic processes, reproduction and cell repair, eukaryotes are often highly specialised in order to perform certain functions and rely upon other cells to fulfil different functions. For exa...
All living organisms require energy. In order to obtain energy, cells within the organisms must go through the processes of cellular respiration and/or fermentation. The way in which “oxidation of glucose leads to ATP production” is emphasized in cellular respiration (Freeman et al., 2014).
Anabolism builds up molecules similar to what can be found in food. It builds up, for example, carbohydrates and proteins. Like catabolism, anabolism also occurs in three stages. The first stage of anabolism creates the parts needed to create the molecules.
The nucleus is a organelle that controls all life activities, especially reproduction. In a basketball stadium, the head coach is like the nucleus. The head coach controls everything that happens especially what his team does. This is how the
The nucleus of a cell keeps the cell going as a result of its the mainframe of a cell therefore it controls what happens inside a cell,what the cell will do and the way the cell is going to be used. Found inside of the nucleoplasm, the nucleolus is a consolidated district of chromatin where ribosome manufacturing happens.
When something gives us energy, it means more than to just give us the required power to work or move along for such a specific task. In biological terms, it means to have your energy be transported through your body and placed by cells into biomolecules. Biomolecules such as lipids and carbohydrates. It then stores that energy in our body.
Our metabolism, “the totality of an organism’s chemical reactions”, manages energy usage and production of cells. We use energy constantly and our metabolism breaks down food through complex chemical reactions into energy our cells
The mitochondria is an organelle which is generally an oval shape and is found inside the cytoplasm and is again apart of the eukaryotic cells. The main function of the mitochondria is to complete cellular respiration; in simple terms it acts like a digestive system to break down essential nutrients and to convert it into energy. This energy is usually found to in ATP which is a rich molecule taken from the energy stored in food. Furthermore, mitochondria stores calcium for signalling activities; such as heat, growth and death. They have two unique membranes and mitochondria isn’t found in human cells like the red blood cells yet liver and muscle cells are filled entirely with mitochondria.

This is a type of reaction where a molecule is broken down into smaller pieces. It is called an anabolic reaction. This experiment is the breakdown of hydrogen peroxide to form water and oxygen in the air. Catalase is found in a cell organelle called the peroxisome. Peroxisomes in animal cells are occupied in the decomposition of
The nucleus contains genetic material that controls all the activities within a cell. A nucleus is made up of D...
