Mg²⁺

Question 9

What is PP_i?

Answer 9

Inorganic Pyrophosphate

Question 10

3 Major Sources of Phosphate Taking Part in Energy Conservation or Energy Capture

Answer 10

1. Oxidative Phosphorylation
2. Glycolysis
3. The Citric Acid Cycle

Question 11

An endergonic reaction is a couple of what reactions for it to proceed forward?

Answer 11

First, glycolysis coupled with hydrolysis of the terminal phosphate of ATP

Question 12

What is the action of Myokinase?

Answer 12

It interconverts Adenine Nucleotides

• ATP + ADP <–Myokinase–> 2 ADP

Question 13

What enzyme is used to make Acetyl-CoA?

Answer 13

Acetyl-CoA Synthetase

Question 14

What is the action of PP_i?

Answer 14

The hydrolysis off PP_i to 2 phosphate ions is utilized in many biochemical pathways to render reactions effectively irreversible.

Question 15

What is the action of Nucleoside Diphosphate (NDP) Kinase?

Answer 15

By means of DNP Kinases, UTP, GTP, & CTP can be synthesized from their diphosphates

• EX: UDP reacts with ATP to form UTP & ADP
