  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?

New cards
31

In the cytosol

Where does glycolysis take place?

New cards
32
  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?

New cards
33
  1. Adds a phosphate group

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

New cards
34

Glycolysis is what kind of pathway

catabolism

New cards
35

1 Glucose leads to how many pyruvate

2

New cards
36

What are the products of glycolysis

2 pyruvate, 2 atp , 2 NADH

New cards
37

How many intermediates are bisphosphorylated

2

New cards
38

What is the first high energy forming reaction catalyzed by?

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

New cards
39

how is a mutase different from an isomerase

the mutase moves the phosphate group to different carbon position

New cards
40

What are pyruvates 2 fates

lactate dehydrogenation and alcohol dehydrogenation

New cards
41

Where is NAD+ regenerated?

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

New cards
42

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

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