What else can I help you with?
Cyanide rotenone and dinitrophenol are often referred to as respiratory poison?
Cyanide, rotenone, and dinitrophenol are considered respiratory poisons because they disrupt the process of cellular respiration by targeting different components of the electron transport chain. This interference prevents the production of ATP, the cell's main energy source, leading to cell death. Cyanide inhibits cytochrome c oxidase, rotenone inhibits complex I, and dinitrophenol disrupts the proton gradient across the inner mitochondrial membrane.
Active transport process by which materials are secreted or expelled from a cell?
Exocytosis is the active transport process by which materials are packaged into vesicles and then released from a cell. During exocytosis, the vesicle membrane fuses with the cell membrane, allowing the contents to be discharged outside the cell.
What stages in the process of aerobic respiration make it an aerobic process?
Aerobic respiration involves glycolysis, the Krebs cycle, and oxidative phosphorylation. The presence of oxygen in the final stage, oxidative phosphorylation, is what makes it an aerobic process. This stage requires oxygen to efficiently produce ATP from the breakdown of glucose.
Which of these processes is used to make the ATP produced by glycolysis?
The process used to make ATP produced by glycolysis is oxidative phosphorylation, which occurs in the mitochondria. This involves the electron transport chain and ATP synthase, where the electrons generated by glycolysis are used to generate ATP.
How can you justify the disappearance of oxygen as a measure of electron transport?
In the electron transport chain Oxygen is the final electron acceptor. Also the Oxygen accepts 2 Hydrogen ions, making water in the process. The dissapearance of Oxygen shows that the electron transport chain is working and that Oxygen is doing its job.
Why do biologists believe glycolysis evolved before the Krebs cycle and electron transport chain?
Biologists believe glycolysis evolved before the Krebs cycle and electron transport chain because glycolysis is a simpler metabolic pathway that can occur in the absence of oxygen. This suggests that glycolysis may have evolved earlier in Earth's history when oxygen levels were low. The Krebs cycle and electron transport chain are more complex and rely on oxygen, indicating they likely evolved later.
Where are the enzymes for electron transport located in bacteria if they don't have internal membranes?
Incorrect: Some bacteria do not have an electron transport chain and just glycolysis. If they do have an electron transport chain, then it would take place in the mitochondria.User response: Actually bacteria do not have a mitochondrium. Their electron transport chain is located inside their cytoplasmic membrane.

The breakdown of glucose for energy is called?
Fermentation

Why mitochondrion is called powerhouse of the cell?
Mitochondria are the powerhouses of cells because they are the epicenter of the electron transport chain. While glycolysis can occur in the cytoplasm, the bulk of energy production takes place due to a hydrogen concentration gradient found in the mitochondria.
Which of these processes is used to make the ATP produced by glycolysis?
The process used to make ATP produced by glycolysis is oxidative phosphorylation, which occurs in the mitochondria. This involves the electron transport chain and ATP synthase, where the electrons generated by glycolysis are used to generate ATP.
How many ATP molecules are produced by the electron transport chain by glycolysis?
A net of two ATP are produced during glycolysis.
Why is oxygen the final electron acceptor in the electron transport chain?
Oxygen is the final electron acceptor in the electron transport chain because it has a high electronegativity, which allows it to efficiently pull electrons towards itself, facilitating the production of ATP in the process of cellular respiration.
How can you justify the disappearance of oxygen as a measure of electron transport?
In the electron transport chain Oxygen is the final electron acceptor. Also the Oxygen accepts 2 Hydrogen ions, making water in the process. The dissapearance of Oxygen shows that the electron transport chain is working and that Oxygen is doing its job.
Which does not take place in the mitochondria of the cell?
Glycolysis. The Krebs cycle and Electron Transport Chain or Oxidative Phosphorylation both occur in the Mitochondria. For photosynthesis, the process takes place in the chloroplasts which are in the mesophyll cells of the leaves. Don't know if this answer is going to help. And because of this i think i m going to have to do my ap bio hw tomoro. thanks a lot.
