Enzymes

Proteins that act as biological catalysts by speeding up chemical reactions so life processes can function.

They are not consumed in the chemical reactions.

• Enzymes

• Substrates

• Lipids

• Amino Acids

Molecules that enzymes break apart or put together (reactants).

• Osmosis

• Active Site

• Enzymes

• Substrate

The specific area of an enzyme that bonds with the substrate for a moment and fits the shape of the substrate exactly.

• Nucleic Acids

• Reactants

• Products

• Active Site

Temporary bonding between the enzyme and the substrate.

• Nucleolus

• Hydrogen Bonding

• Active Site

• Enzyme-Substate Complex

The new substances formed from the substrate.

• Reactants

NGSS.HS-LS1-6

NGSS.HS-LS1-7

The shape of the active site ensuring that enzymes usually work with only one kind of substrate.

• Enzyme Specificity

• Products

• Substrate

• Enzymes

The amount of energy needed to start a chemical reaction.

This is significantly lowered by enzymes, speeding up chemical reactions so life can exist.

• Induction Energy

• Products

• Active Site

• Activation Energy

NGSS.HS-PS1-4

To bend a protein so it no longer functions.

• Activate

• Enzyme

• Denature

• Substrate

Tags

NGSS.HS-LS1-1

The measure of acidity in a substance.

• pH

• Meter

• Net neutrality

• Oxygen concentration

Tags

NGSS.MS-PS1-2

A pH that is too high or low denatures an enzyme

so the active site cannot bind efficiently with the substrate.

Enzymes are designed to work at specific acid or base levels.

• Enzymes and temperature

• Excess oxygen

• Enzymes and pH

• Excess Hydrogen
