Define Carnivore

Define Basal metabolic rate
The minimum amount of energy required by the body in a day
Proteins are made of?
Amino acids
In what order does the body prefer to burn the macronutrients?
Carbohydrates, fat, protein.
When proteins are eaten, they are broken down into their amino acids. If your cells are short on amino acids, what happens to the amino acids that come from the proteins you eat? What happens if your cells have plenty of amino acids?
If your cells do not have enough amino acids, the amino acids, the amino acids from the proteins you eat are sent to your cells so that our cells can make the proteins they need if your cells have plenty of amino acids, the amino acids from the proteins you eat are either burned for energy or converted into carbohydrates or fats
Why is it important to eat either animal protein or a wide variety of plant protein?
There are several amino acids our bodies can’t make, there for we must get them from food
Which type of animal has a higher BMR and endothermic animal or an ectothermic animal?

Which type of animal cannot be active on a very cold day: an endothermic animal or an ectothermic animal?
Ectothermic
