Efficency and alternatives in respiration

Question 1

BMR

Answer 1

cellular respiration is only 41% eficient
Basal metabolic rate: energy needed just to survive

Question 2

creatine phosphate

Answer 2

• excess ATP phosphorylates creatine –> creatine phosphate + ADp
• stored in muscle cells
• important for rapid changes in required atp

Question 3

Glycogen

Answer 3

• glycogen (carb) is hydrolyzed (glycogeneolysis) and phosphorylated into glucose-1-phosphate
  –> rearranged glucose-1-phosphate into glucose-6-phosphate

Question 4

fats

Answer 4

fats hydrolyze into glycerol + fatty acids

• glycerol: enters glycolysis by becoming DHAP in liver
  -fatty acids: beta oxidation and enter kreb’s cycle

ketosis

Question 5

Protiens

Answer 5

hydrolyzed into amino acids
- converted to pyruvate, acetyl, other substances in kreb’s cycle

de novo gluconeogenisis
- low carb diets: body breaks down protien–> muslce wastes away quicker than fat
- faster to burn protiens then fats

Question 6

alternatives to glucose full list

Answer 6

glucose: glycogen and glycerol (fats)
pyruvate: amino acids
acetyl Coa: fatty acids (beta oxidation) and amino acids
kreb’s: amino acids
