Cellular Respiration Chapter 6.4

Question 1

What is Glycolysis

Answer 1

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

Question 2

Because glycolysis does not require o2 it can be in

Answer 2

Glycolysis can take place in aerobic and anaerobic environments

Question 3

Describe the first 5 steps of Glycolisis

Answer 3

GLUCOSE ACTIVATION

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

Question 4

The last 5 steps of Glycolysis

Answer 4

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.

Question 5

The net gain of Gly

Answer 5

pyruvate
2 NADHS per molecule of glucose
2 ATPS ‘’ ‘’

Question 6

Substrate-Level Phosphorylation

Answer 6

The means by which Glycolysis produces ATP.

A high energy donor molecule enzyme physically transfers a phosphate group to ADP,forming ATP

Question 7

The opposite of Substrate-Level Phosphorylation

Answer 7

Chemismotic Phosphorylation

Question 8

Chemismotic Phosphorylation

Answer 8

Requires a proton gradient to add a phosphate group to ADP
