Please define the term "organic" in a reference to what it contains.

Back 1

Compounds containing carbon that are found in living organisms are regarded as organic.

Front 9

Is water made or use in a condensation reaction?

Back 9

water is the by-product

Front 10

Give two examples of a Monosaccharide.

Back 10

Glucose, Fructose and Ribose

Front 11

Give two examples of a Disaccharide

Back 11

Sucrose (glucose+fructose)
Maltose (glucose+glucose)

Front 12

Give two examples of a Polyscharide

Back 12

Starch (made of glucose subunits)
Glycogen (made of glucose subunits but linked differently from starch)

Front 13

What are three functions of lipids?

Back 13

energy storage - in the form of fat in humans and oil in plants

heat insulation - a layer of fat under the skin reduces heat loss

Buoyancy - lipids are less dense than water so it helps animals to float

Front 14

state a function of a monosaccharide

Back 14

Transport - glucose is carried by the blood to transport energy to cells throughout the body

Front 15

state a function of a polysaccharide

Back 15

energy storage - energy is stored in the form of glycogen in liver cells

Front 16

Between Carbohydrates and Lipids, which are usually used for energy storage over short periods?

Back 16

Carbohydrates

Front 17

give two examples of energy storage through lipids

Back 17

1. lipids contain more energy per gram than carbohydrates, so stores of lipid are lighter than stores of carbohydrates that contain the same amount of energy

2. lipids are insoluble in water, so they do not cause problems with osmosis in cells

Front 18

give two example of energy storage through carbohydrates

Back 18

1. Carbohydrates are soluble in water so they are easier to transport to and from the store

2. Carbohydrates are more easily digested then lipids so the energy stored by them can be released more rapidly.

Front 20

what does a polypeptide consist of?

Back 20

a chain of many amino acids

Front 21

what does a disaccharide consist of?

Back 21

the linking of two monosaccharides

Front 22

what does a polysaccharide consist of?

Back 22

after a disccharide is formed and more and more monosaccharides are linked to the disaccharide a polysaccharide is created

Front 23

what does a glyceride consist of?

Back 23

when fatty acids are linked to glycerol by condensation reactions

Front 24

water is added to polypeptides, what is created?

Back 24

dipetides or amino acids

Front 25

when water is added to Polysaccharides, what is created?

Back 25

disaccharides or monosaccharides

Front 26

when water is added to glycerides, what is created

Back 26

fatty acids and glycerol
