Glycolysis

Question 1

Glycolysis is one of the principal pathways generating what? and where is it present?

Answer 1

Glycolysis is one of the principal pathways generating ATP in cells and is present in all cell types in the human body

Question 2

What is the central role of glycolysis?

Answer 2

It is related to the availability of glucose as a fuel in blood and its ability to generate ATP in the presence and absence of oxygen

Question 3

What can glycolysis lead to/ generate? and what does that lead to?

Answer 3

Lead to the generation of pyruvate which is subsequently oxidized in the Krebbs-cycle or to the generation of lactate which is released from the cell

Question 4

What are the principal energies which containing products of glycolysis?

Answer 4

ATP and NADH

Question 5

When can NADH be used to generate energy

Answer 5

ONLY in the presence of oxygen

Question 6

When is NADH produced?

Answer 6

Only produced under aerobic conditions, but not in the absence of oxygen, where it is used to generate lactate

Question 7

Glycolysis is not the only pathway in the body to use glucose what are others

Answer 7

Glucose can be oxidised in the pentose-phosphate pathway, which is important for the generation of NADPH or it can stored by forming glycogen

Question 8

After a meal what is the main fuel for many cells in the body?

Answer 8

Glucose
