What enzyme changes Pyruvate to Lactate?

1. Glycolysis is the oxidation of glucose. Pyruvate is the end product.

2. Provides ATP. NADH is also produced.

3. In aerobic organisms, glycolysis yields precursors to the Krebs Cycle & Electron Transport System

What are the 3 purposes of Glycoysis?

In the cytosol

Where does glycolysis take place?

1. Bring glucose into the cell

2. Change glucose into an "energy rich sugar"

What are the 2 functions of the first half of glycolysis?

1. Adds a phosphate group

How does the first half of glycolysis "trap" glucose in the cell?

Glycolysis is what kind of pathway

catabolism

1 Glucose leads to how many pyruvate

2

What are the products of glycolysis

2 pyruvate, 2 atp , 2 NADH

How many intermediates are bisphosphorylated

2

What is the first high energy forming reaction catalyzed by?

glyceraldehyde 3 phosphate (inorganic P added to NAD+-->NADH)

how is a mutase different from an isomerase

the mutase moves the phosphate group to different carbon position

What are pyruvates 2 fates

lactate dehydrogenation and alcohol dehydrogenation

Where is NAD+ regenerated?

lactate fermentation of the skeletal muscle ( through contraction) and Electron Transport Chain

Where is another location for NAD+ regeneration that is less beneficial for human cells?

yeast through alcohol dehydrogenation (through metabolism) and Electron Transport Chain
