the starting molecule for glycolysis is..
which of the following is NOT a product of glycolysis: NADH, pyruvic acid, ATP, glucose

what passes high-energy electrons into the ETC?
the energy of the electrons passing along the ETC is used to make what?
which process does NOT release energy from glucose: glycolysis, photosynthesis, fermentation, or cellular respiration?
photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back
