Lesson 3 (Biology Q2)

ATP-ADP Cycle

Adenine

double ring of carbons and nitrogen atoms

Ribose

five carbon sugar

Phosphate

Three ? units is linked together by covalent bonds

ATP

Energy currency used by all organisms

Adenosine Triphosphate

ATP meaning

metabolic reactions

ATP acts as the fuel for nearly all ? inside the cell

ATP

Energy released from the breakdown of food and transferred in molecules

Oxidation

removal of electrons or protons from coenzymes

Reduction

addition of electrons to a molecule

Nicotinamide Adenine Dinucleotide

NAD stands for?

Flavin Adenine Dinucleotide

FAD stands for ?

phosphate

When an ATP molecule is broken down by an enzyme, third ? group as an ion releases energy made available to do work in the cell

adenosine diphosphate (ADP) and a phosphate ion

What are the products of ATP breakdown

ADP and phosphate

? ion can be reconstituted to form ATP when synthesis energy is available
