What else can I help you with?
Is ATP synthase a protein?
Yes, ATP synthase is a protein.
When ATP synthase in activated it adds a phosphate group to what molecule?
ATP synthase catalyzes the addition of a phosphate group to an ADP molecule. ADP + ATP synthase + P --> ATP + ATP synthase (ATP synthase on both sides of the equation indicates that, as an enzyme, it is not used up in the reaction.)
Is ATP synthase an integral protein?
Yes, ATP synthase is an integral protein.
Is ATP synthase an enzyme responsible for the production of ATP in cells?
Yes, ATP synthase is an enzyme that plays a key role in the production of ATP in cells.
Complex I can be inhibited exclusively by?
Rotenone
Where are the catalytic knobs of ATP synthase located?
The catalytic knobs of ATP synthase would be located on the stromal side of the membrane. Protons travel through ATP synthase from the thylakoid space to the stroma.
What are enzymes that creates ATP called?
ATP Synthase
Which of the following is false about the structure and function of ATP synthase?
At least 10 protons pass through ATP synthase in order to make a molecule of ATP.
An enzyme citrate synthase in the Krebs cycle is inhibited by ATP What type of inhibition would this be?
Citrate synthase is inhibited by ATP. Obviously, the Krebs cycle produces ATP. This is the first step and one of the major regulatory steps in the pathway. If the cell has plenty of ATP, then it wouldn't need to keep making it, thus the pathway needs to be shut off. ATP inhibits the enzyme to shut off the pathway. This is an example of feedback inhibition (you can also call it negative inhibition or even product inhibition). Feedback inhibition is when the products of a certain biochemical pathway inhibit earlier enzymes, shutting down the pathway.
Complex IV can be inhibited exclusively by?
Cyanide
Complex III can be inhibited exclusively by?
Antimycin
What do mitochondiral and thylakoid membranes have in common?
They both use ATP synthase proteins in ATP production
