Understanding Cellular Respiration and ATP Production

What does ATP stand for and what is its role in the cell?

• Adenosine triphosphonate, enzyme activator

• Adenosine tetraphosphate, secondary energy carrier

• Adenine thymine phosphate, DNA component

• Adenosine triphosphate, primary energy carrier

Where does glycolysis occur within the cell?

• Ribosome

• Cytoplasm

• Nucleus

• Mitochondria

What is the role of NADH in cellular respiration?

• To transfer electrons

• To produce glucose

• To consume oxygen

• To generate carbon dioxide

What is the main purpose of the Krebs Cycle?

• To create oxygen

• To produce glucose

• To generate ATP, NADH, and FADH2

• To consume ATP

What does the enzyme ATP synthase do?

• Converts ADP to ATP

• Transfers electrons

• Synthesizes DNA

• Breaks down ATP

What is the final electron acceptor in the electron transport chain?

• Oxygen

• Carbon dioxide

• Glucose

• Water

Why is it important not to memorize a specific number of ATP produced?

• The number can vary based on cellular conditions

• ATP is not important for cell function

• Memorization is discouraged in science

• The number is always constant

How does fermentation differ from aerobic respiration?

• It requires oxygen

• It only occurs in animal cells

• It does not require oxygen

• It produces more ATP

What can cause a block in ATP production, according to the video?

• Excess glucose

• Oxygen surplus

• Cyanide poisoning

• Low NADH levels

What potential benefit does understanding mitochondrial function have?

• Increasing oxygen production

• Improving plant growth

• Developing treatments for diseases

• Enhancing photosynthesis
