Class Topics
Title Anat Phys 5/3/07
Objectives

• To learn about glycolysis and carbohydrate
  metabolism.

• Glycolysis Quiz
• Review Krebs cycle
• Notes
• Electron Transport Chain/chemiosmosis
• Fuels
• Prejudices, it is well known, are most difficult
  to eradicate from the heart whose soil has never
  been loosened or fertilized by education they
  grow there, firm as weeds among the stones.

Krebs Cycle Review

• What enters and what leaves?

6
Totals per molecule of glucoseRemember -
pyruvate has 3 carbons

• ATP _______
• NADH _______
• FADH2 _______
• Wheres the oxygen?

CO2____
7
Chemiosmosis

• Electron Transport Chain (system)
• Occurs on the inner membrane of the mitochondrion
• Takes high energy electrons from NADH and FADH2
  and transfers it to ATP is the process of making
  water from excess Hydrogen ions, oxygen, and
  electrons (depleted of energy)

Animations

• University of Connecticut
• Smith College
• Virtual Cell Animation
• Concepts in Biochemistry

10
Total Energy

• 4 ATP from glycolysis
• -2 ATP to initiate glycolysis
• 2 ATP from TCA cycle
• 4 ATP from NADH of glycolysis
• 24 ATP from NADH of TCA cycle
• 4 ATP from FADH2 of TCA cycle

11
Fuels

• Carbohydrates
• starches and sugars into glucose - released into
  blood
• muscles take in glucose use or store as
  glycogen
• Excess carbs are stored as fat
• liver stores glycogen for brain
• glycogen can only be formed from carbohydrates

12
Fuels

• Protein
• gluconeogenesis
• formation of glucose from amino acids
• not a main source of energy
• Atkins diet
• ketosis

13
Fuels

• Fats
• at least twice as much energy as carbs per gram
• released from adipose tissue and sent to area
  needing energy
• Brain cannot use fats as fuel - only glucose
