please answer these biochemistry questions: I asked these but the expert only answered one question and skipped these 2. true/false: decreased oxaloacetate would cause increased flux though the citric acid cycle I put false since it would decrease since normal levels of OAA needed for CAC to run properly 3. true/false: all odd numbered fatty acids enter CAC as acetyl COA I put false since if its odd numbered wouldn't they need to be converted first?
