Answer 1

Glucouse and Galactose.

Question 2

What is Endocytosis?

Answer 2

Question 4

What is active transport?

Answer 4

The movement of molecules across a membrane that requires energy.

Question 5

Compare between saturated fats and unsaturated fats.

Answer 5

*Saturated fats: Has the maximum number of hydrogens. Solid at room temprature.
*Unsaturated fats: Has fewer than the maximum number of hydrogens at the double bond.
Liquid at room temprature.

Question 6

What is the function of golgi apparatus?

Answer 6

Receives products form the ER through transport vesicles, refines it, stores and then distribute it to the other organelles or the plasma membrane.

Question 7

What is the difference between DNA and RNA?

Answer 7

DNA sugar is deoxyribose. RNA sugar is ribose.
DNA has the base thymine(T). RNA has the base uracil(U).
DNA exists as double helix. RNA is single-stranded.

Question 8

What is common between prokaryotic cell and eukaryotic cell?

Answer 8

They both have:
*Cytosol
*Plasma membrane
*Chromosomes
*Ribosomes

Question 9

What is the function of ribosomes?

Answer 9

Responsible for protein synthesis.

Question 10

What is the function of nucleus?

Answer 10

Control center of the cell and contains the DNA that stores information and produce protein.

Question 11

What is the cell theory?

Answer 11

All living things are composed of cells and that all cells come from earlier cells.

Question 12

What is hydrolysis?

Answer 12

Breaks bonds between monomers and adds a molecule of water.

Question 13

What is the complimentary strand of DNA that has AGTCCGC?

Answer 13

TCAGGCG.

Question 14

List 2 differnces between eukaryotic cell and prokaryotic cell.

Answer 14

Eukaryotic cells have organelles.
Eukaryotes have nucleus that contain dna while prokaryotes have no nucleus and the dna is in a Nucleoid

Question 15

What is exocytosis?

Answer 15

The movement of large molecules using vesicles out of the cytoplasm through plasma membrane.

Question 16

What is passive transport?

Answer 16

The movement of a molecule across the membrane that doesn’t require energy.

Question 17

What are 2 organelles that have their own DNA?

Answer 17

Mitochondrea and Chloroplast.

Question 18

How do enzyme speed up a chemical reaction?

Answer 18

by reducing the amount of activation energy required to break the bonds of reactant molecules.

Question 19

What is cytoplasm?

Answer 19

region between the nucleus and plasma membrane. It consists of cytosol+organelles.
