Chapter 8 - How Cells Make ATP

Question 1

Glycolysis

Answer 1

📌A series of chemical reactions in the cytoplasm of a cell that break down glucose into two molecules of pyruvic  acid
📌4 ATP molecules are produced
📌2 ATP molecules are used in the process
📌 the NET gain is 2 ATP molecules
📌 2 NADH molecules are produced

Question 2

Cellular respiration

Answer 2

A process of taking oxygen and glucose and turning them into ATP, energy for the body

Happens in 3 phases

1. Glycolysis
2. Citric Acid Cycle( Krebs cycle)
3. Electron Transport Chain(ETC)

Question 3

Fermentation

Answer 3

📌is a process that follows Glycolysis when Oxygen is not present
📌 2 types of fermentation
- Lactic acid fermentation
- Alcoholic fermentation

Question 4

Lactic Acid Fermentation

Answer 4

• Under anaerobic conditions, the Krebs cycle and ETC cannot happen
• Two molecules of pyruvate uses NADH to form two molecules of lactic acid
• This releases NAD+, which can be used for glycolysis to continue happening
• This yields ATP(not as much) that can be used for energy

Question 5

Alcoholic Fermentation

Answer 5

• Used by yeast cells
• Produces CO2 and Ethyl Alcohol
• Yields 2 ATP
