Front 1

Role of Sulfur in Plants, Animals and Prokaryotes?

Back 1

In some amino acids

Front 2

Role of Calcium in Plants, Animals and Prokaryotes?

Back 2

Co-factor in some enzymes
Animals: components in bones

Front 3

Role of Phosphorous in Plants, Animals and Prokaryotes?

Back 3

Phosphate groups in ATP

Front 4

Role of Iron in Plants, Animals and Prokaryotes?

Back 4

In cytochromes
Animals: haemoglobin

Front 5

Role of Sodium in Plants, Animals and Prokaryotes?

Back 5

in membrane function
Animal: sending nerve impulses

Front 6

Water molecules held together by what bonds

Back 6

H(polar covalent) and split second H bonds

Front 7

Thermal Props of H2O

Back 7

-High specific heat (absorbs/gives off lots of heat w/out changing temp)

-Water content as temp stablizer

-Absorbs great deal of heat when evaporated

Front 8

What is cohesion?

Back 8

-When molecules of the same type are attracted to each other

Front 9

Cohesive properties of H20

Back 9

-H20=highly cohesive (Due to polar covalent bonding)

Explains:
-water spill : comes tog.
-surface tension: "Walk on water"
-How able to move in column in plant vascular tissue.

Front 10

Solvent Properties of H20

Back 10

-Water is excellent solvent of other polar molecules

-Lipids however are not polar and body has way of dealing with.

Front 11

2.Fructose
3.Galactose

Front 12

Front 15

Three functions of lipids

Back 15

1.energy storage
2.thermal insulation-blubber
3.Phospholipids make up a bilayer to form a cell membrane

Front 16

Compare the use of carbohydrates and lipids in energy storage

Back 16

Lipids store about twice as much energy as carbohydrates
Lipids are used for long-term energy storage whereas carbohydrates are used for short-term energy storage
Lipids are insoluble whereas carbohydrates are often soluble. This means that lipids do not have an osmotic effect on organisms.

Front 17

Names molecules and subcomponents

Back 17

-carbs (Monosaccharides)
-Lipids (Glycerol and fatty acids)
-Proteins (amino acids)
-Nucelic acids (Nucelotides)

Lactose (di) function?

Back 19

Makes up some of the solutes in milk

Front 20

Glycogen (Poly) function?

Back 20

Stores glucose in liver and muscles

Front 21

Fructose (mono) function?

Back 21

Found in many fruits (makes sweet)

Front 22

Sucrose (Di) function?

Back 22

Often transported from leaves of plants to other locations in plants by vascular tissue

Front 23

Cellulose (poly) function?

Back 23

One of the primary components of plant cell walls

Front 24
