Biol 152 Test 2

Once they have been processed through the citric acid cycle, the acetyl-CoA molecules from a single glucose molecule produce:

2 ATP, 6 NADH, 4 CO2.

Reactions with a negative ΔG that release energy and proceed spontaneously (Catabolic)

exergonic

In cellular respiration, glucose is _____ to CO2 and oxygen is _____ to water.

oxidized; reduced

ATP consists of..

ATP is a nucleotide composed of adenine, ribose, and three phosphate groups.

allosteric enzyme

An enzyme whose activity is affected by binding a molecule at a site other than the active site. Typically, allosteric enzymes change their shape on binding an activator or inhibitor.

Energy

Capacity for a organism to do work

Free Energy

Energy is stored in the bonds, the stronger the more stable

Kinetic Energy

Motion

Potential Energy

Stored Energy

beta-oxidation

The breakdown of fatty acids takes place

reactions with a positive ΔG that require an input of energy and are not spontaneous (anabolic)

endergonic

Organic molecules store _____energy in their _____ bonds.

potential; covalent

How Can Enzymes Increase Reaction Rates?

the enzyme lowers the energy needed for the activation energy
