Enzymes

Glucose, Sucrose

Cholesterol, Butter

Hemoglobin, Insulin

They slow down reactions

They speed up reactions without being consumed

They change the products of reactions

They stop reactions completely

Enzymes are organic catalysts made of protein

Most enzymes end in -ase

Enzymes increase the activation energy of reactions

Enzymes make reactions happen slower

To lower the activation energy required for the reaction

To increase the temperature of the reaction

To provide energy for the reaction

To change the products of the reaction

pH, temperature, and concentration of enzymes and substrates

Light intensity and sound

Amount of oxygen and carbon dioxide

Size of the enzyme

The enzyme activity increases indefinitely

The enzyme becomes denatured and activity decreases

The enzyme activity remains constant

The enzyme changes into a different enzyme

High temperature

Low substrate concentration

Changes in pH

Low enzyme concentration

The rate of reaction decreases as substrate concentration increases

The rate of reaction increases indefinitely with substrate concentration

The rate of reaction increases to a point and then levels off

The rate of reaction is not affected by substrate concentration

2 - I kinda get it

4 - I can explain it to a friend
