Aerobic vs Anaerobic Exercise

What is a common benefit of regular aerobic exercise?

• Increased muscle mass

• Improved cardiovascular endurance

• Enhanced explosive power

• Increased bone density

Which of the following is a typical duration for aerobic exercise to be effective?

• Less than 5 minutes

• 5 to 10 minutes

• 20 to 60 minutes

• More than 2 hours

Cell respiration with no oxygen.

Inefficient production of ATP. 2-4 ATP per Molecule of Glucose

Intense activities for humans.

ie. Sprinting 100 meters.

• Chloroplasts

• Aerobic Respiration

• Photosynthesis

• Anaerobic Cellular Respiration

Which of the below is a consequence of lactic acid production?

• Increased flexibility of muscles

• Increased strength

• Increased muscular pain & fatigue

A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event

• As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen. 

• As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.

• The cells will never run out of oxygen if the weightlifter is breathing.

• As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.
