What is Glycolysis

A universal pathway that splits glucose into two 3 carbon molecules named Pyruvate.
. It requires 10 steps in the cytoplasm non of which require O2

2

Because glycolysis does not require o2 it can be in

Glycolysis can take place in aerobic and anaerobic environments

3

Describe the first 5 steps of Glycolisis

GLUCOSE ACTIVATION

ATP is used to activate glucose redistributing energy in the molecule and splitting it in half.

4

The last 5 steps of Glycolysis

ENERGY EXTRACTION

Stores some energy in 2 molecules of electron carrier, NADH.
Other steps extract more of the energy, regaining the two ATP molecules invested earlier plus producing two more.

5

The net gain of Gly

pyruvate
2 NADHS per molecule of glucose
2 ATPS '' ''

6

Substrate-Level Phosphorylation

The means by which Glycolysis produces ATP.
A high energy donor molecule enzyme physically transfers a phosphate group to ADP,forming ATP

7

The opposite of Substrate-Level Phosphorylation

Chemismotic Phosphorylation

8

Chemismotic Phosphorylation

Requires a proton gradient to add a phosphate group to ADP
