Glycolysis

The first step in getting energy in the cell by breaking down glucose is known as

• the Krebs cycle
• electron transport
• fermentation
• glycolysis

Which of the following is the correct chemical equation for Cellular Respiration?

• C₆H₁₂O₆ + 6O₂ --> 6CO₂ + 6 H₂O + ATP Energy

• C₆H₁₂O₆ + H₂O --> 6CO₂ + 6 6O₂ + ATP Energy

• 6CO₂ + 6 H₂O + Light Energy --> C₆H₁₂O₆ + 6O₂

• C₆H₁₂O₆ + 6CO₂ --> 6O₂ + 6 H₂O + ATP Energy

Which of the following is not a requirement for glycolysis?

• Oxygen
• ATP
• NAD⁺
• Glucose

Glycolysis results in the net gain of:

• 2 ATP
• 4 ATP
• 4 NADH
• 2 Acetyl CoA

Where does glycolysis occur?

• mitochondrial matrix
• cytoplasm
• inner membrane of mitochondria
• outer membrane of mitochondria

What is the main function of glycolysis?

• To rearrange the glucose molecule to be broken down

• To split the glucose molecule to release energy

• To recreate acetyl CoA for the krebs cycle

• To absorb and store energy in ATP molecules

There are 10 steps in glycolysis, how many enzymes catalyze these steps?

• 8

• 9

• 10

• 11

What are the products of glycolysis?

• 2 ATP, 2 NADPH, 2 pyruvate

• 2 ADP, 2 NADH, 2 pyruvate

• 2 ATP, 2 NADH, 2 pyruvate

• 2 ADP, 2 NADPH, 2 pyruvate

How does glycolysis lead to ATP synthesis?

• Glucose provides the phosphate for ADP to synthesize ATP

• Glycolysis splits the glucose molecule to create G3P

• High energy electrons are stored in NADH for the ETC

• Acetyl CoA is synthesized for the Krebs cycle
