Introduction: Metabolism

Organisms get their energy to do work from ___________ energy.

• solar energy

• thermal energy

• chemical energy

• nuclear energy

A → B + C

• Anabolic

• Catabolic

The type of reaction that occurs when a molecule is broken down by an enzyme.

• Metabolic

• Anabolic

• Catabolic

• Reduction

A + B → AB + Energy

This is what type of reaction?

• exergonic

• endergonic

Which of the following is true for anabolic pathways?

• they do not depend on enzymes

• they consume energy to build polymers from monomers

• they are usually spontaneous chemical reactions

• They release energy as they degrade polymers to monomers

The breakdown of glucose molecules to release energy.

• catabolic pathway

• endergonic pathway

• kinetic pathway

• anabolic pathway

Main cellular energy molecule

• ATP

• cAMP

• ADP

ATP is called a cell’s “energy currency” because

• ATP catalyzes all metabolic reactions

• glucose is made of ATP

• most of the energy that drives metabolism is supplied by ATP

• ATP allows one organelle to be exchanged for another between cells

Protein Synthesis, Photosynthesis, and other Biosynthetic pathways.

• Anabolic Pathways

• Catabolic Pathways

Is the sum of all your body’s catabolic and anabolic reactions.

• activation energy

• metabolism

• anabolic reaction

• catabolic reaction
