Question 0

How many nutrients to humans require

Answer 0

6 proteins carbohydrates lipids fats water vitamins and minerals

Question 1

Nutrient

Answer 1

A chemical that must be obtained by an organism from its environment in order to survive

Question 2

What are nutrients used for

Answer 2

So growth and repair and making energy

Question 3

Metabolism

Answer 3

All the chemical reactions that occur in living organisms that are needed to maintain life

Question 4

Catabolism

Answer 4

Metabolic reactions that break down larger molecules into smaller subunits

Question 5

Anabolism

Answer 5

Metabolic reactions that uses energy to produce larger molecules from smaller subunits

Question 6

Carbohydrates

Answer 6

Molecules contains atoms of carbon hydrogen and oxygen are in a 1 to 2 to 1 ratio glucose C6 H 12 O6
Represents the bodies most important source of energy
there are three types of carbohydrates

Question 7

What are the three types of carbs

Answer 7

Monosaccharides
disaccharides
and polysaccharides

Question 8

Monosaccharides

Answer 8

Made up of a single sugar molecule like glucose or fructose

Question 9

Disaccharides

Answer 9

Made up of two sugar molecules like sucrose table sugar or lactose

Question 10

Polysaccharides

Answer 10

Complex carbohydrate made up of many sugars linked together starch for plants cellulose and glycogen for animals

Question 11

Proteins

Answer 11

For movement structure enzymes to new oxygen sources of energy defense antibodies
20 different types of amino acids building blocks of proteins 12 essential amino acids that can’t be made food input needed eight nonessential can be made inside body meat eggs cheese for animals being until seeds nuts plants carbs and protein can both provide energy excess can store protein

Question 12

Lipids

Answer 12

Divided into three categories 
A fats oil waxes 
B phospholipids cell membrane 
C steroids estrogen testosterone 
lipids perform long-term energy storage installation of internal organs cell membrane formation make up hormones, steroids

Question 13

Fats

Answer 13

Most common lipid made up of two structural units which are a glycerol molecule and three fatty acid this molecule is called try glycerides they can be saturated or unsaturated

Question 14

Saturated fats

Answer 14

Linear molecule, packed tight together solid at room temperature, no double bond so molecule is full of hydrogen atoms comes from animals, difficult to be broken down by body example lard butter

Question 15

Unsaturated fats

Answer 15

Bent shaped molecule can’t pack close together liquid at room temperature hydrogen double bonds not full with hydrogen atoms come from plants easily broken down by cells example canola and olive oil
