How many food calories can a human burn up in an hour by exercising at this rate? (remember that only 20.0 % of the food energy
blsea [12.9K]

Human can produce a maximum mechanical power of 1/3 hp (horse-power).

Horse power is a unit of power, it equals 746 watt (watt is also a power unit, known to be equal to a joule per second)


So:

1 ph = 746 watt = 746 J/s

1/3 ph = 248.6 J/s

we're looking for the calories, so

1 joule = 0.239006 calories


So human produce a maximum mechanical power of:

248.6 J/s = 82.88 calories per second.


We're looking for the number of calories consumed in three hours, so:

82.88 cal/s = 82.88 cal/s * 3600 s * 3 = 895200 calories = 895.2 kilocalories (food calories).


The number of food calories is 895.2 food calories

D. increasing the number of mitochondria

Explanation:

The mitochondria are membrane-bound cellular organelles found in the cell of an eukaryote. Mitochondrion is responsible for the production of energy since the process which releases the energy (cellular respiration) occurs in it.

In an experimental procedure whereby the amount of energy which is produced by a cell is about to be increased will involve the increase of the number of mitochondria in that cell. Since more mitochondria means more energy production.
