● What is lipogenesis?. Answer: When your body makes fat from non-
fat substances
● ATP. Answer: Produced in the mitochondria
Produced by use of a high proton concentration in the inner membrane
space
Produced via the conversion of ADP and inorganic phosphate by the
ATP synthase
NOT!! Is generated at a rate exactly proportional to weight to the 3/4
power
