Step 1: Glycolosis

Question 1

Where does Glycolosis occur?

Answer 1

In the cytoplasm

Question 2

Describe the process of Glycolosis:

Answer 2

1. The glucose molecule (C6H12O6) is broken down into two 3 carbon molecules known as G3P.
2. The G3P is broken down into Pyruvate 3 (another 3 carbon molecule.)

Question 3

What happened to the Hydrogen molecules in the glucose?

Answer 3

4 out of the 12 hydrogens left the glucose and become bonded with NAD; this is due to NAD being a hydrogen receptor.

The NAD then becomes NADH2

Question 4

What is oxidation?
What is Reduction?

(This is tricky)

Answer 4

Oxidation- when a hydrogen molecule is lost
Reduction- when a hydrogen molecule is gained.

In Glycolosis, the glucose is oxidized and the NAD is reduced

Question 5

Where are the four places where the energy is stored in Glycolosis?

Answer 5

Pyruvate ( this is most of energy)
ATP
Heat
NADH2

Question 6

How many ATPs are gained during Glycolosis?

Answer 6

4 gross gain of ATP
2 ATP are lost due to energy needed to run the reaction.

2 ATP are the net gain in Glycolysis
