It’s a challenging class for most students, but it should be manageable if you’re aware of what you’re facing.

Where is PDC most active?

PDC is a large multi-enzyme complex located within the matrix compartment of mitochondria, and links glycolysis to the tricarboxylic acid cycle by catalyzing the irreversible oxidative decarboxylation of pyruvate, which leads to the generation of CO2, NADH, and acetyl-CoA.

Do colleges accept 3 on AP test?

Many colleges accept a score of 4 or 5 on an AP exam as college credit in that subject area. In some cases, even a 3 is accepted for college credit. The more selective an institution is, the more likely they are to require higher AP scores in order to receive college credit.

The transport of pyruvate into the mitochondria is via the transport protein pyruvate translocase. The carbon dioxide produced by this reaction is nonpolar and small, and can diffuse out of the mitochondria and out of the cell.

Does acetyl-CoA inhibit PDH?

PDH kinase is stimulated by NADH and acetyl-CoA. It is inhibited by pyruvate. The PDC is regulated by covalent modification through the action of a specific kinase and phosphatase; the kinase and phosphatase are regulated by changes in NADH, acetyl-CoA, pyruvate, and insulin.
