Day 3 Biology

Homeostasis

• allows for a wildly fluctuating internal environment

• is impossible in vertebrates

• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation

The area that the substrate fits into on the enzyme is called the:

• Active Site
• Allosteric Site
• DiSulphide Bridge
• β-Pleated Sheet

Enzymes speed up reaction rates by LOWERING:

• Activation Energy
• pH
• Hydrogen Bonds
• Kinetic Energy

The molecule an enzyme is working on is called the:

• Substrate
• Solvent
• Allosteric Inhibitor
• CoEnzyme

What is the purpose of an enzyme?

• control how many reactions occur

• raise activation energy

• give permission for the reaction

• speed up chemical reactions

An enzyme speeds up a reaction by

• lowering the activation energy.
• raising the activation energy.
• releasing energy.
• absorbing energy.
