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
Proteins is used to build and repair cells.
Protein can be found in every living cell and it is very
important building block in the body. Protein supply amino acids which were
being used to create and repair cells, enzymes, red blood cells, antibodies and
tissues. In the body, protein functions by maintaining fluid balance and
transportation substances. Protein can be gotten from meat, dairy products, soyabeans,
nuts, beans and certain grains. However,
protein from meat and other animal products are known as complete protein.

Im sorry if it's wrong but that's what I would go with
Answer:
Enzymes are proteins that increase (only) the rate of chemical reactions converting substrate into product.
Catalysts are substances that increase or decrease the rate of a chemical reaction but still remain unchanged.
