Cell Respiration & Metabolism

What is Respiration?

• The process by which Energy in the Form ATP is formed by an Energy Source

In Cellular Respiration Energy is released by?

• By the Stepwise breakdown of Glucose, and other molecules (proteins & fats)

Glucose is the most ef….?

• Efficient source for ATP Production

What are the 2 Subcategories of Metabolism?

• Catabolic
  - Big Molecules Made into Smaller Molecule

• Anabolic
  - Smaller Molecules Make Big

Is Energy Transfer ever 100% efficient?

• No

In Anabolic Reactions Dehydration Synthesis is used to build up larger molecules what process is used in Catabolic Reactions?

• Hydrolysis

What is Oxidation?

• Molecule either gains an Oxygen or loses a Hydrogen

What is a Reduction?

• Where a structure gains Energy

Describe Anaerobic Respiration

• No 02

• Occurs in Cytosol

• Glycolysis

• Only 2 ATP Produced

• Produces Lactic Acid

Describe Aerobic Respiration

• Uses 02

• 1Glucose = 36-38 ATP

• Mitochondria = Essential

Glycolysis is the first?

• First Step in Anaerobic Respiration

Pyruvic Acid is the pre?

• Precursor to Anaerobic Respiration

Aerobic Respiration Diagram

. Each glucose molecule can produce how many pyruvic molecules?

• 2

When Pyruvic Acid enters the Mitochondria what it is converted to?

• Acetyl COA
