Below are some statements about the TCA Cycle. Which statement is true based on what we have learned in the class?   Question 16 options:   Oxaloacetate can be replenished from pyruvate carboxylation catalyzed by pyruvate carboxylase.   The catabolism of proteins can only feed into the TCA cycle at one point, which is Acetyl-CoA.   Acetyl-CoA has transporter proteins and can be transported directly from matrix to cytoplasm (for fatty acid synthesis).   In TCA cycle, both Acetyl-CoA and Succinyl-CoA hydrolysis reactions are coupled with ATP/GTP synthesis.
