Exploring Anaerobic Glycolysis in Sport

What is the primary energy source for muscles during anaerobic glycolysis?

• Fatty acids

• Glucose

• Amino acids

• Oxygen

Which by-product is formed as a result of anaerobic glycolysis in muscles?

• Carbon dioxide

• Water

• Lactic acid

• Urea

How does anaerobic glycolysis differ from aerobic respiration?

• It requires oxygen

• It produces more ATP

• It occurs in the mitochondria

• It does not require oxygen

What is the typical duration for which anaerobic glycolysis can sustain high-intensity activity?

• 2-3 seconds

• 10 seconds-2 minutes

• 2-3 minutes

• 10-15 minutes

Which of the following sports is primarily anaerobic in nature?

• Marathon running

• Long-distance cycling

• 200-metre sprint

• Triathlon

What role do enzymes play in anaerobic glycolysis?

• They provide energy

• They act as catalysts

• They store glucose

• They transport oxygen

Which of the following is a consequence of lactic acid accumulation in muscles?

• Increased energy production

• Muscle fatigue

• Enhanced endurance

• Improved flexibility

What is the main advantage of anaerobic glycolysis during short bursts of activity?

• It uses oxygen efficiently

• It prevents muscle fatigue

• It provides energy quickly

• It produces a large amount of ATP

Which enzyme is primarily responsible for the breakdown of glucose in anaerobic glycolysis?

• Pyruvate kinase

• Phosphofructokinase

• Hexokinase

• Lactate dehydrogenase

What happens to pyruvate at the end of anaerobic glycolysis in muscle cells?

• It is converted to acetyl-CoA

• It is used in the Krebs cycle

• It is converted to lactic acid

• It is stored as glycogen
