This is the term for how fast metabolism happens.
Metabolic rate.
These chemicals break food down into their component parts.
What are Enzymes?
This is what is converted to energy by the process of metabolism.
Food!
Enzymes reduce protein to this.
Amino acids.
Enzymes reduce fat to this.
Fatty acids.
Fatty acids, amino acids, and sugars are transported to cells by _________.
Blood/the circulatory system
This is the most common way our body stores excess energy.
Fat
Stored as fat.
Metabolism can be thought of as a balancing act between these two processes.
Building up/breaking down body tissue
OR
Anabolism/Catabolism
These are two specific tasks of anabolism:
Building up of tissue
Storing of energy
Repairing cells and tissue
These are two specific tasks of catabolism:
Fuel anabolism
Heat the body
Enable muscles to contract/move
What happens if metabolism ceases?
Death
Two organs that help release the waste products of metabolism are:
(Any two of the below)
Skin
Kidneys
Lungs
Intestines
This is the pancreas' role in metabolism.
Release enzymes to determine if anabolism or catabolism is needed, depending on blood glucose level.

True or false: 70% of the calories we need to stay alive are used for sleeping, breathing, and other essential tasks.
True
Does metabolism happen while you sleep?
Yes
This is one way to control your metabolic rate.
(Any one of the below)
Adequate sleep
Small meals throughout the day

What is metabolism?
Chemical reactions within the body that convert food into energy.
Glucose is one kind of ______.
Sugar
Explain why apple juice and whole apples do not affect your metabolism in the same way.
Apple juice: concentrated sugar with no fibre. A body cannot metabolize the sugar fast enough and it is turned into fat.
Whole apple: The fibre in the apple slows digestions and absorption of the sugars, creating lasting energy that is released slowly.
