Front 3

Anabolism

Back 3

Build up reactions that build up large molecules out of smaller ones.

Front 4

Catalyst

Back 4

Any substance that increases the rate of chemical reactions.

Front 5

Enzyme

Back 5

A protein that increases the rate of biochemical reactions.

Front 6

Substrate

Back 6

Any substance acted upon by an enzyme

Front 7

Active site

Back 7

Region on an enzyme where catalytic activity takes place.

Front 8

Glycolysis

Back 8

This metabolic pathway includes:

Occurs in the cytosol of cell

Nets 2 molecules of ATP

Converts a molecule of glucose into 2 molecules of pyruvate acid and provides hydrogen ions to electron carriers for ETS in the form of 2 NADH molecules

Front 9

TCA cycle (krebs' or citric cycle)

Back 9

This occurs in mitochondrial matrix

Produces 2 ATP

Provides hydrogen ions for electron carriers for ETS in the form of NADH and FADH2 molecules

Produces carbon dioxide as waste
