False
What is nutrition?
How is metabolism related to it?
1) The process of consuming nutrients for good health
2) Metabolism is the rate at which you process foods to create energy (how fast you consume the nutrients)
What is cellular respiration?
1) The process by which the body uses glucose (food) to release stored energy.
Explanation: Cellular respiration is the body’s way of breaking down glucose (sugar) to release the energy that’s stored in it for the cells to use.
What is excretion?
What are some examples of this?
1) Getting rid of waste
2) Sweat, urine, feces, saliva
