c1.1 enzymes and metabolism

Enzymes

Protein based catalysts that speed up chemical reactions

Metabolism

Sum of all enzyme catalyzed reactions happening in a cell

Enzymes are

Subtrate specific / each substrate needs its own enzyme

Why r enzymes important

Reactions would occur but too slow to sustain life Enzymes speed up reactions

Types of metabolic reactions

Anabolic building bonds

Catabolic break bonds

Induced fit model

Substrate bond to active site

Active sight changes slightly

It affects the bonding allowing it to catalyze products

Products release

Active site returns into its original shape

Globular proteins

3d insoluble proteins that are round and folded

Denaturation

Permenant change to the active it wont be able to catalyze (from temp/ph.certain concentration)
