Q

From our previous experiment the starch diffuse from inside of the tube to the outside? Explain why

A

No starch did not move from inside the tube to outside of the two because starch is a big molecule and the water did not change colors

20
Q

On our previous experiment did water diffuse from outside of the tube to the inside of the tube? Explain why

A

Yes the water did diffuse from the beaker to inside of the tube. The reason why is because there was less than a hundred percent of water in the tube. So the water moved from high concentration to low concentration making the tube weigh more.

21
Q

From our last experiment does Iodine diffuse from outside of the bag to inside of the tube?

A

Yes there was 1% of water in the beaker and 0% instube, this caused the iodine to diffuse from high concentration to low concentration. The color in the tube turn black. Also iodine is a small molecule.

22
Q

What happens when the water diffuses out of the cytoplasm and out of the central vacuole?

A

The chloroplast are seen closer to the center of the cell

23
Q

Many amino acids linked form a?

A

Polypeptide= a protein

24
Q

Fatty acids are the monomers for?

A

Fats and oils

25
Q

Lipids form

A

Fats, waxes & oil

26
Q

Lipids have

A

Fewer oxygen

27
Q

Fats and oils are

A

Triglycerides

28
Q

Glycerol is formed by

A

Three fatty acids + dehydration synthesis

29
Q

Molecular formula for lipids

A

C16 h12 02

30
Q

Three examples of common polysaccharides

A

Cellulose starch glycogen

31
Q

How does the liver store glucose

A

It stores it as glycogen

32
Q

what is the molecular formula for glucose

A

C6 h-12 06

33
Q

How is ATP made

A

Fructose converted to glucose and then forms ATP

34
Q

How is a molecular formula written

A

Always alphabetically

35
Q

What happens when a monomer gives away their water

A

They attach and become polymers

36
Q

What is the reaction of a molecule becoming a larger molecule

A

Dehydration synthesis

37
Q

When the water splits a larger molecule into smaller molecules the reaction is called?

A

Hydrolysis

38
Q

Saturated fats in the molecular formula have what type of bonds

A

Single bonds

39
Q

What type of fats cause cardiovascular disease?

A

Saturated fats

40
Q

unsaturated fats have more or less bonds

A

Double bonds between carbon atoms and fewer hydrogen atoms

41
Q

Saturated fats have less or more hydrogen atoms

A

More hydrogen atoms and single bonded carbons

42
Q

Characteristics of some protein

A

Enzymes speed up reactions, each enzyme shape allows it to speed up one type of chemical reaction, stomach enzymes break protein into dipeptides, they function differently in PH conditions

43
Q

Name three organic molecules in nucleic acid

A

DNA RNA ADP

44
Q

What is denatured

A

Change in three-dimensional shape of A protein

45
Q

In water with the concentration of hydrogen atoms be greater or smaller then water

A

Greater than water
