Overview of Metabolism

Question 1

What is metabolism?

Answer 1

Series of enzyme reactions within cells to convert fuels into useful energy

Question 2

What is Catabolism?

Answer 2

Generates ATP and NADH

ends in -Lysis

Question 3

What is Anabolism?

Answer 3

Uses ATP, GTP and UTP (mainly in cytosol)

ends in -Genesis

Question 4

Full equation for mitochondrial respiration?

Answer 4

C6H12O6 + 6 O2 –> 6 CO2 + 6 H2O + 30 ATP + 2 GTP

Question 5

Features of ATP?

Answer 5

The energy of the cell
Adenosine Triphosphate
stable at 6-9 pH
Phosphoanhydride bond can be broken by hydrolysis to form ADP+Pi and energy
It drives pumps, transporters, contractive events and movement

Question 6

Endergonic and Exergonic reactions?

Answer 6

Endergonic is where energy is absorbed

Exergonic is where energy is released

Question 7

Allosteric inhibition and activation?

Answer 7

Inhibition is where a molecules blocks an enzyme

Activation is where molecules stimulate enzymes
