Flashcards in Glycolysis Deck (13):
1

Glycolysis

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

2

Kinase

The enzyme that carries out Phosphorylation

3

Phosphofructokinase (PFK)

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

4

What is the end product of Glycolysis?

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

5

Reduction

Adding Electrons

6

Oxidation

Releases Electrons

7

Redox Reaction

When Reduction and Oxidation take place

8

Lactate Dehydrogenase (LDH)

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

9

What does Lactate do in Glycolysis

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.

10

Obligate Anaerobs

Oxygen is toxic to these cells (builds up free radicals)
-bacteria and fungi

11

Faculative Anaerobs

Cells that can live with or without oxygen

12

Anaerobic

Cells that don't require oxygen

13

Fermentation

converts sugars to acids
- pyruvate to lactate in animals
-pyruvate to ethanol in plants
