Glycolysis

Question 1

Glycolysis

Answer 1

Breaking down glucose to make ATP

• used in every cell
• -found in bacterial cells, used in plant cells, done in our own cells
• takes place in the cytosol (not in organelles)
• involves 9 chemical reactions
• it is anaerobic
• nets 2 ATP atoms from 1 glucose
• nets 2 NADH atoms from 1 glucose

Question 2

Kinase

Answer 2

The enzyme that carries out Phosphorylation

Question 3

Phosphofructokinase (PFK)

Answer 3

A regulatory enzyme (allosteric enzyme) 
- Used in the 3rd step of glycolysis 
2 Co-factors
-ATP-slows down the reaction
-AMP-speeds up the reaction

Question 4

What is the end product of Glycolysis?

Answer 4

2 Pyruvate (3 Carbon compounds)
Net 2 ATP
Net 2 NADH

Question 5

Reduction

Answer 5

Adding Electrons

Question 6

Oxidation

Answer 6

Releases Electrons

Question 7

Redox Reaction

Answer 7

When Reduction and Oxidation take place

Question 8

Lactate Dehydrogenase (LDH)

Answer 8

Is the enzyme that carries out fermentation of Pyruvate to Lactate.

Question 9

What does Lactate do in Glycolysis

Answer 9

It lowers the pH.

-As pH drops the enzymes won’t work like they should. It will stop the enzymes from working, shutting down glycolysis.

Question 10

Obligate Anaerobs

Answer 10

Oxygen is toxic to these cells (builds up free radicals)

-bacteria and fungi

Question 11

Faculative Anaerobs

Answer 11

Cells that can live with or without oxygen

Question 12

Anaerobic

Answer 12

Cells that don’t require oxygen

Question 13

Fermentation

Answer 13

converts sugars to acids

• pyruvate to lactate in animals
• pyruvate to ethanol in plants
