Question

Fill in the blanks. glycolysis leads to the production of ______ and two molecules of atp. in the absence of oxygen, fermentation can lead to the production of ______. glycolysis plus the krebs cycle (citric acid cycle) can convert the carbons of glucose to xxxxxx , storing the energy as atp, xxxxx and xxxxx.

Answer 1

pyruvate; lactic acid, CO2, NADH, FADH2

In glycolysis, glucose is converted into two molecules of pyruvate.

In the absence of oxygen, the fermentation occurs, pyruvate is reduced by NAD+  leading to the production of lactic acid.

Glycolysis plus the krebs cycle can convert the carbons of glucose to CO₂ (CO2 is the waste product that you release when you exhale)

Some of the energy is stored in the form of electrons and is captured in formation of high-energy compound, NADH and FADH2. (The NAD+ and FAD are reduced forming NADH and FADH₂).
NADH and FADH2 are then transported to the electron transport chain, where their high energy electrons will produce more ATP.
