Glycolysis produces 2 ATP molecules, through what process are these ATP molecules made?(ANS- Substrate level phosphorylation
What product of beta oxidation is able to enter the citric acid cycle?(ANS- AcetylCoA
What process is shared between anaerobic and aerobic metabolism?(ANS- glycolysis
A defect occurs that prevents pyruvate from converting to lactate under anaerobic conditions - what is a possible consequence?(ANS- glycolysis stops because NAD+ levels are too low
What differentiates aerobic from anaerobic cellular metabolism?(ANS- utilization of 02 as an electron acceptor
