a/anaerobic respiration

1. In which condition is anaerobic respiration most likely to occur in humans?

• • During sleep

• • While eating

• • During intense exercise

• • While reading

What is the primary reason muscles may switch to anaerobic respiration?

• • Lack of carbon dioxide

• • Lack of oxygen

• • Lack of water

• • Lack of glucose

1. What is the main consequence of lactic acid buildup in muscles?

• • Increased energy levels

• • Muscle fatigue and pain

• • Enhanced muscle growth

• • Improved oxygen supply

1. What is the initial substrate used in anaerobic respiration in humans?

• • Protein

• • Fatty acids

• • Amino acids

• • Glucose

1. What is the main purpose of aerobic respiration?

• • To produce glucose

• • To create oxygen

• • To convert carbon dioxide into oxygen

• • To generate energy in the form of ATP

1. Where does aerobic respiration take place in a eukaryotic cell?

• • Ribosomes

• • Mitochondria

• • Cytoplasm

• • Nucleus

1. What are the end products of aerobic respiration?

• • Glucose and oxygen

• • Lactic acid and ATP

• • Ethanol and carbon dioxide

• • Carbon dioxide, water, and ATP

1. How many ATP molecules are produced from one molecule of glucose during aerobic respiration?

• 4 ATP

• • 36-38 ATP

• 50 ATP

• 2 ATP

respiration that takes place in the presence of oxygen is called____________ respiration.
