Q
  1. Why does glucose need to be phosphorylated (Pi added) before glycolysis can occur?
A

The glucose becomes more reactive and splits into two 3-carbon molecules called triose phosphate.

Q
  1. Why does NAD become reduced?
A

Because it gains a hydrogen to form NADH.

Q
  1. How many molecules of ATP are produced when triose phosphate is converted to pyruvate?
A

2 (this happens twice though so there are four in total)

Q
  1. What is the net gain of ATP, reduced NAD and pyruvate molecules?
A

2 ATP because 4 were made but 2 were used at the start of the process, 2 NADH and 2 pyruvate.

Q
  1. What are coenzymes? Give an example.
A

Molecules that are needed for enzymes to function. They transfer chemical groups such as hydrogen atoms or acetate. Examples are NAD, FAD and coenzymeA.
