Question 1

Carbs, lipids and protein can all be ___ to make ATP

Answer 1

Carbs protein and lipids are all be catabolized and used for energy

Question 2

Protein catabolism

Answer 2

1. Deamination: An amino group is removed becoming ammonia

The rest of the protein is converted into molecules used in glycolysis and Krebs

Question 3

Lipid Catabolism

Answer 3

• Lipids are broken down into glycerol and fatty acids
• A process called gluconeogenesis convert glycerol into glucose that will undergo glycolysis
• Fatty acids are broken down into acetyl-CoA and can go through the Krebs cycle to produce ATP

Question 4

Ethanol Fermentation

Answer 4

• Fermentation occurs after pyruvate oxidation, and it occurs will oxygen is low (anaerobic)
• CO2 is removed from pyruvate and forms acetaldehyde
• NADH is oxidizing to NAD+, reducing acetaldehyde making ethanol

Question 5

When is Ethanol Fermentation used

Answer 5

• used in the production of breads and pastries, as well as beer, wine and liquor
• Yeast cells ferment glucose from starch, and release CO2, and ethanol
• Co, bubbles cause bread to rise in the baking process, and the ethanol evaporates

Question 6

Lactic Acid Fermentation

Answer 6

• During exercise, oxygen is depleted in our cells too quickly to keep up with aerobic respiration
• Instead, NADH gives its electrons to pyruvate, becoming NAD+ and allowing glycolysis to continue
• This results in pyruvate becoming lactate, causing stiffness, soreness and burning in our muscles

Question 7

Exercise Physiology

Answer 7

VO2 Max measures the maximum amount of oxygen your body can use m per kg of body weight in one minute during exercise, indicating your aerobic fitness level.
