Question

1)what types of exercise would you choose and why?

2)What is the best explanation for why your heart rate increases during exercise?

a)Because the heart is a muscle and when you exercise you exercise all your muscles.

b)Because you need to move more oxygen around your body

c)Because your heart beating faster lets your lungs expand faster

d)Because you need to move more ATP around your body

3)Why does a person’s respiratory rate remain elevated after they stop exercising?

a)Their muscle cells are breaking down lots of ATP

b)Their muscle cells are making lots of ATP

c)Their muscle cells are doing lots of fermentation

d)Their muscle cells are making lots of glucose

4)If you are working out vigorously to the point that you can no longer talk (breathing hard), your muscle cells will probably start doing fermentation.

a) true

b)false

5)Your cells can break down fats using fermentation or cellular respiration.

a)true

b)false

6)E. coli can do both fermentation and cellular respiration. You have two cultures of E. coli. You give them the same amount of food (glucose) and grow them at the same temperature. One culture is grown in open air, the other is placed in an oxygen free bag. The two cultures are growing at the same rate (producing new cells at the same rate). What is happening to the amount of glucose available to each culture?

a)Both cultures are using glucose at the same rate

b)The culture in the air is using glucose faster than the culture without oxygen

c)

The culture without oxygen is using glucose faster than the culture in open air

Answer 1

As per our guidelines i answer first four questions.

1) i i mostly prefer aerobic exercises. They include running, swimming, dancing etc... They are very good for our Cardiovascular system. They reduce type 2 diabetes, high blood pressure and even reduce the risk of cancer. Squats, pushups, abdominal crunches etc.. can also be preferred. Aerobic exercise also aids our sleep, reduce asthma, Strengthen immunity health etc...

2) option c is the best answer for this question. Reason for the answer is the body needs more oxygen to function during exercise. Fast pulses helps so that more blood gets out of the body.

3) the best answer is option c. After the exercise the body cells need more Oxygen to be in a normal condition. Lactic acid should be converted into pyruvate. For this process oxygen is needed.

4) the answer is true. Conversion of lactic acid to pyruvate need more oxygen. This reaction happening as soon as the body getting into a normal state.
