Many rings of amino acids

Question 14

How many types of amino acids are in a polypeptide

Answer 14

20

Question 15

What holds amino acids together

Answer 15

Hydrogen bonds

Question 16

Polypeptides are

Answer 16

3 dimensional

Question 17

Peptides are linked together through what type of bonds

Answer 17

Covalent peptide bonds

Question 18

From our previous experiment does glucose diffuse from inside the tube to the outside? Explain why?

Answer 18

Yes it moves from high concentration to low concentration the test strips showed the green pigment

Question 19

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

Answer 19

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

Question 20

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

Answer 20

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.

Question 21

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

Answer 21

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.

Question 22

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

Answer 22

The chloroplast are seen closer to the center of the cell

Question 23

Many amino acids linked form a?

Answer 23

Polypeptide= a protein

Question 41

Saturated fats have less or more hydrogen atoms

Answer 41

More hydrogen atoms and single bonded carbons

Question 42

Characteristics of some protein
