What happens in citric acid cycle

Answer 1

The acetyl group from acetyl co-enzyme A combines with oxoloacetate to form citrate.

Question 2

During a series…

Answer 2

Question 3

Where does the citric acid cycle occur

Answer 3

In the matrix of the mitochondria

Question 4

What do dehydrogenase enzymes do?

Answer 4

Dehydrogenase enzymes remove hydrogen ions and electrons and pass them to the co-enzyme NAD, forming NADH. Occurs both glycolysis and citric acid cycle

Question 5

Hydrogen ions and electrons from…

Answer 5

NADH are passed to the electron transport chain on the inner mitochondrial membrane.
