Mitochondria require oxygen and glucose to carry out cellular respiration, a process which generates energy in the form of ATP for the cell. Oxygen is used as the final electron acceptor in the electron transport chain, while glucose is broken down in a series of reactions to produce ATP.

Which organelle cause respiration in a plant cell?
Cellular respiration occurs in 3 steps (Glycolysis, the citric acid cycle, and the electron transport chain) Glycolysis takes place in the cytoplasm of the cell and the citric acid cycle and the electron transport chain happen in the mitochondria.
Why do sperm cell have a high density of mitochondria while the human cheek cell have only a few mitocondria?
Sperm cells require a lot of energy to swim to the egg for fertilization, hence they have a high density of mitochondria to produce energy through respiration. Cheek cells do not require as much energy as sperm cells, so they have fewer mitochondria.
What happens to cell respiration when photosynthesis stops?
When photosynthesis stops, the supply of glucose decreases, causing a decrease in the amount of available energy for cellular respiration. As a result, cellular respiration slows down since there is less glucose to break down in the mitochondria to produce ATP. This can lead to a decrease in energy production and possibly impact the overall functionality of the cell.
Why is cyanide a universal poison effective in all organisms with mitochondria?
Cyanide inhibits cytochrome c oxidase, an enzyme involved in the electron transport chain of mitochondria, disrupting cellular respiration and leading to cellular asphyxiation. This mechanism affects all organisms with mitochondria, making cyanide a universal poison that can cause rapid and severe toxicity in various species.
What is the difference between cellular respiration and fermantation?
Cellular respiration is an aerobic process that occurs in the presence of oxygen and results in the production of ATP. Fermentation is an anaerobic process that occurs in the absence of oxygen and results in the production of ATP and byproducts like lactic acid or alcohol. Cellular respiration produces more ATP per glucose molecule compared to fermentation.
Which organelle would cause fatigue?
The mitochondria is the organelle that can cause fatigue. Mitochondria are responsible for producing energy in the form of ATP through cellular respiration. If mitochondria are not functioning efficiently, it can lead to decreased energy production and result in fatigue.
Which organelle cause respiration in a plant cell?
Cellular respiration occurs in 3 steps (Glycolysis, the citric acid cycle, and the electron transport chain) Glycolysis takes place in the cytoplasm of the cell and the citric acid cycle and the electron transport chain happen in the mitochondria.
What does cyanide cause a malfunction of?
Cyanide inhibits the functioning of cytochrome c oxidase, an enzyme involved in the electron transport chain in mitochondria. This disrupts cellular respiration and leads to a decrease in ATP production, ultimately causing cells to be unable to generate energy.
What type of cell contains mitochondria?
all body cells, as they cause respiration Eukaryotes.
Is carbon dioxide a gas produced by cellular respiration?
yes cause it is a gas every body knows that
What is the difference in the VO2 Max between men and women?
genetically males have a higher VO2 max that females because males have a greater muscle mass that females. Mitochondria are the site of cellular respiration and the majority of them are located within muscle tissues in the body. If there are more sites for cellular respiration than the body will be able to keep at an aerobic level of fitness for longer because the body can remove a higher volume of oxygen from the bloodstream. This would cause a person to maintain a longer state of aerobic respiration and therefore have a higher VO2 max.

A defect in which organelle would cause fatigue?
A defect in the mitochondria, which are responsible for generating energy in the form of adenosine triphosphate (ATP), could lead to fatigue. Mitochondrial dysfunction can result in decreased energy production, affecting cellular processes that require energy, such as muscle contraction and nerve signal transmission, leading to fatigue.
Does cellular respiration cause most organic molecules?
I wouldn't say that. The main purpose of respiration, that in biochemistry is known as "oxidative phosphorylation" is to produce ATP molecules. A complete chain of an oxidative phosphorylation pathway goes from a molecule of glucose that is degraded into smaller molecules, passing through tricarboxylic acid cycle and a redox loop mechanism (in mitochondria) to produce molecules of water and CO2.
