BioChem Test 2 Ch 17 Glycolysis

What is an inhibitor to step 3?

ATP

What is an inhibitor to step 9?

ATP

What are the three fates of pyruvate?

Reduction to lactate(anaerobic), Reduction to ethanol(microbes), oxidation and decarboxylation to acetyl-CoA(aerobic organisms)

What steps of glycolysis are control points?

Step 1, 3, and 9.

Which step in Glycolysis can not be reversed?

Step 3

What is the first step in glycolysis that energy is made?

Step 7, ATP/ADP is made.

How many steps is Glycolysis?

10 steps.

How many steps is the generation of ethanol to pyruvate? What does it produce?

2. It regenerates NAD+

Is glycolysis exergonic or endergonic?

Both, some steps are endergonic and some steps are exergonic. However, overall it is exergonic and occurs with a large decrease in free energy.

What is glycolysis?

First stage of glucose catabolism that produces ATP, NADH, and pyruvate.

What is an inhibitor in step 1?

Glucose-6-phosphate

Where does glycolysis occur?

In the cytoplasm

What is a key regulatory enzyme in glycolysis and what step does it occur in?

Phosphofructokinase. Step 3.
