Question 1

What is the structure of proteins

Answer 1

polymers of amino acids

Question 2

what are the two main functions of steroids

Answer 2

important part of cell membranes, signaling molecules

Question 3

ribosomes

Answer 3

protein synthesis,read rna, read the genetic instructions to produce proteins

Question 4

lysosomes

Answer 4

digestive system of the cell,hydrolytic enzymes that makes it easier to break down fats, proteins, sugars and nucleic acids

Question 5

messenger RNA transfers information

Answer 5

from DNA to ribosomes

Question 6

transcription

Answer 6

DNA to RNA to MRNA to RNA polymerase

Question 7

mitotic cell division

Answer 7

results in two identical daughter cells to their parent cells

Question 8

what is the role of water in photosynthesis?

Answer 8

supply electrons in the light reaction

Question 9

light reactions

Answer 9

solar light converted into ATP Cell absorbs the light and uses the light energy to split a water molecule and transfers the electrons producing NADH and ATP

Question 10

calvin cycle

Answer 10

NADH and ATP created by the light reactions to produce sugar.

Question 11

Crossing over

Answer 11

cells give each other the genetic materials mitosis this does not occur
