Carbohydrate metabolism 1b

Glycolysis occurs in the mitochondria

• True

• False

All 10 reactions of glycolysis are important and reversible

• True

• False

The first 5 steps in glycolysis are called "energy-investment" steps as ATP is required to drive them

• True

• False

The end product of glycolysis is _____________

• starch

• glucose

• acetyl coA

• pyruvate

The NADH that is formed in glycolysis can go on to produce more ATPs by oxidative phosphorylation in the mitochondria

• True

• False

The enzymes that regulate glycolysis are allosteric enzymes

• True

• False

• Maybe

• Does not matter

Glycolysis means breakdown of GLUCOSE. Other sugars such as fructose cannot enter glycolysis pathway

• True

• False

Muscle uses Fructokinase enzyme to allow fructose entry into glycolysis

• True

• False

_____________ is a regulatory enzyme of glycolysis pathway

• Hexokinase (HK)

• Phosphofructokinase (PFK)

• Pyruvate Kinase (PK)

• all the above

Part of the glycolytic pathway can proceed in the reverse direction (as they contain many reversible steps)

• True

• False
