Animal Nutrition

Question 1

Purpose of Nutrition? (2)

Answer 1

Development + survival.

–> Growth & repair
(new cells, maintaining tissue, repairing injury)

–> energy (ATP)
(need energy to perform vital functions - breathing/ moving)

Question 2

What is food? Organic/Inorganic?

Answer 2

Organic: (animal + plant origin)
Carbohydrates, Proteins, Fats
–> provides calories (E/ATP)
–> provides building blocks build/replace ^^ in each cell

Inorganic: DNA, Vitamins, Minerals
–> no calories (no E)
–> co-factors to building blocks

Question 3

Amino Acids, main facts (3)

Answer 3

Proteins made of amino acids

9 Essential to humans
–> must gain through diet, released during digestion

CANNOT BE STORED

Question 4

Carbohydrates main facts

Answer 4

All carbs are made of sugars.
–> provide most E (ATP) for the body

Simple carbs (sugars) easy to absorb.
Complex carbs (starches harder to digest, fibers indigestible)

CAN BE STORED

Excess glucose –> Glycogen (liver, kidney, muscles)

Question 5

Fatty Acids main facts

Answer 5

Essential nutrients:
–> used for energy storage
–> aid absorption of fat soluble vitamins (A, D, E, K)

1) Saturated fats (solid dairy)
2) Mono unsaturated fats (liquids/oil)
3) Poly unsaturated fats (essential for brain/heart health (omega 3 fatty acid))

4) Trans fats (artificially creates via rehydration, margarine)

Question 6

White vs Brown Fat

Answer 6

White fat (fat-filled cells adipocytes - connective tissue)
–> commonly used energy storage, 1 droplet/cell slow access

Brown adipose tissue (heat production)
–> non-shivering thermogenesis, multiple lipid droplets/organelle fast access

Question 7

Vitamins

Answer 7

13 essential (humans)

1) Lipo (Fat) soluble (stored in fatty tissue & liver)
2) Water soluble (not stored, need to be consumed regularly - Vit C)
