Topic 1 - Intro to Nutrition & Massage Therapy Flashcards
The study of nutrients in food, how the body uses them and the relationship between diet, health and disease.
Nutrition
Nutrition describes the science behind how what we eat affects our body’s ________ processes.
Cellular
Although there is no one size fits all model when it comes to nutrition and diet, it is understood that ____________ and/or ________ in different nutrients, vitamins and minerals can lead to changes in bodily function.
Deficiencies
Excesses
The reason what we eat has an effect on our bodies is due to the cellular processes of __________.
Metabolism
The chemical process by which the body changes food and drink into energy in order to maintain life and allow for proper cellular functions.
Metabolism
What are the 2 main types of metabolic reactions that take place at a cellular level?
1) Catabolic Reactions
2) Anabolic Reactions
Metabolic reactions that break down large organic molecules into smaller particles, therefore releasing the energy found in the chemical bonds and creating ATP.
Catabolic Reactions
Depending on what molecule is broken during catabolic reactions (e.g. carbohydrates, proteins, fats), the _____ in ATP will differ.
Yield
T/F - Catabolic reactions are 100% efficient.
False - Catabolic reactions are NOT 100% efficient.
Usually the energy yielded from catabolic reactions is only about ___% ATP.
40%
T/F - Catabolic reactions are highly hormonally regulated.
True
A hormone that increases blood glucose levels by breaking down fats and proteins.
Cortisol
A hormone that stimulates glycogen breakdown in the liver.
Glucagon
A hormone that stimulates heart rate and respiratory rate, therefore leading to molecule breakdown to increase free glucose.
Adrenaline (aka. Epinephrine)
Metabolic reactions that involve the joining of small molecules to create larger ones. These processes will require ATP that was formed from other reactions.
Anabolic Reactions
Anabolic reactions ______ new molecules, cells and tissues (e.g. protein synthesis in muscle growth, repair and development).
Create
T/F - Anabolic reactions are slightly hormonally regulated.
False - Anabolic reactions are HIGHLY hormonally regulated.
A hormone that stimulates the growth of cells, tissues and bones.
Growth Hormone
A hormone that stimulates the growth of muscle and bone when inhibiting cell death (apoptosis).
Insulin-Like Growth Factor
