Hello everyone. Today for my speaking assignment, I will be speaking to you all about the mitochondrion because I don’t know what else to talk about. For the first part, I am just going to summarize what I know and won’t be going in depth with it as much. Anyways, as most people know, the mitochondrion is the powerhouse of the cell. Mitochondrion is singular while the plural version is mitochondria, which is the one people tend to say and it’s not wrong either way. It is an organelle found in most eukaryotic cells. In 1890, it was discovered by German pathologist Richard Altmann and was called “bioblast” at the time. People also were very skeptical at the time about his findings of the granules and even harshly criticized Altmann until the …show more content…
Another important part of the mitochondria is the enfolding of the inner membrane which is called the cristae. The more the cristae folds, the more surface area will be used for synthesizing ATP. It also contains its own DNA and ribosomes. The main purpose of the mitochondria is to supply the cell with energy. Other purpose are cellular communication, differentiation, growth and cell death. That is the mitochondria.
Energy is required for cells to perform various cellular activities to function such as growth and reproduction. That process of breaking organic compound, which will be food in this case, into oxygen to be used to convert into Adenosine Triphosphate or ATP for energy. Specifically this would be called Aerobic Respiration as the process uses oxygen. It’s literally how we get energy from eating and such. There are three process that occur: glycolysis, the Kreb Cycle and the Electron Transport Chain. This occurs in and outside of the mitochondria. For bacterial, the process will occur in the membrane sometimes without the presence of oxygen which is called anaerobic respiration. The first process is glycolysis which occurs in the cytosol of the cell. The food that we eat will be broken down into glucose. Glucose, a six
Cellular respiration is a chemical reaction used to create energy for all cells. The chemical formula for cellular respiration is glucose(sugar)+Oxygen=Carbon Dioxide+Water+ATP(energy) or C6H12+6O2=6CO2+6H2O+ energy. So what it is is sugar and
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).
Organelles work together to carry out life processes and functions. Each organelle has a certain responsibility to carry out. Organelles are always working diligently to maintain a cell’s internal process and functions. Firstly, the “brain” of the cell is the nucleus. The nucleus administrates all of the cell activities. And, found within the nucleus there is genetic material called chromosomes. Secondly, the nuclear membrane surrounds the nucleus. Additionally, the mitochondria makes ATP energy from food. The lysosomes has digestive enzymes that help break food down. Furthermore, the ribosomes make protein. Then, the Golgi apparatus process and package the
Because the body, namely the “brain, heart, liver, kidneys, pancreas, and skeletal muscle, demand a finely tuned capacity for energy and lots of it, these tissues possess more mitochondria” (parkridge). When the mitochondria are not properly functioning for these organs, cell damage can occur.
The mitochondria produces food for the cell by converting energy the cell needs. The mitochondria and the nucleus are two organelles within a cell that have many of the same similarities. Both organelles are made of two membranes. These layers isolate within the organelle all things considered, yet have protein channels that permit things to go in and out. Both contain DNA material that conveys qualities that encode for proteins. Both have qualities that make ribosomes, the machines that read the guidelines in RNA to make
for a cell to function as part of cellular respiration. ATP is needed to power
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.
Aerobic requires oxygen and takes place inside the mitochondria of iving cells. The energy is stored as adenosine triphosphate (ATP) Aerobic respiration produces 2890KJ/Mole or 38ATP. This is much more than anaerobic. The
According to our text, Campbell Essential Biology with Physiology, 2010, pg. 78. 94. Cellular respiration is stated as “The aerobic harvesting of energy from food molecules; the energy-releasing chemical breakdown of food molecules, such as glucose, and the storage of potential energy in a form that cells can use to perform work; involves glycolysis, the citric acid cycle, the electron transport chain, and chemiosmosis”.
Energy production- The most important function of mitochondria is energy production in the form of ATP. The raw materials are food materials and tissues which are broken down in catabolism. These molecules transferred to mitochondria for further processes. In inner membrane they have electrical charges then they help in producton of ATP (Phosphorylaton) by combine with oxygen (Oxidaton) through five electron transport chain complexes. So this overall
ECOSYSTEMS: Microbes obtain energy from their environment. Like humans, many microbes do this by eating plant and animal material. A typical microbe buffet consists of waste from humans and other animals, dead plants and animals, and food scraps. Bacteria, fungi and algae all take part in decomposing — or breaking down — this waste material. Without them, the world would quickly be overrun with discarded food scraps, raw sewage and dead organisms.
Oxygen (O) is one of the most important ions present in the body, making up 61% of the body’s mass. It aids in the destruction of harmful bacteria, while preserving the bacteria that is beneficial for the body. Oxygen takes on its role, and transfers the bacteria absorbed into the lungs, to the cells, allowing for cell respiration. Oxygen allows for the replacement of old cells, protection of the new ones, production of energy from the food, and decomposition of other foods (“Oxygen and Human Body,” n.d.). Oxygen is also vital to produce an activity known as metabolism, which is ‘the sum of the physical and chemical processes in an organism by which its material substance is ...
