Lesson 2-4

Question 1

It controls all the chemical activities of the cell. The nucleic materials (DNA and RNA) are the principal molecules responsible for this actions.​

Answer 1

Nucleus

Question 2

a jellylike, clear substance that fills the entire cell’s volume. Consists 90% of water.Contains protein, amino acids and glucose

Answer 2

Cytoplasm

Question 3

provides space for important chemical reactions/activities and help move chemicals to their proper destinations

Answer 3

Endoplasmic Recticulum (ER)

Question 4

smallest organelles of cell and responsible for protein synthesis

Answer 4

Ribosome

Question 5

Powerhouse of the cell. They contain enzymes that aid the cell in drawing energy from glucose.

Answer 5

Mitochondria

Question 6

It stores water and other materials for use by the cells. Big on plant cells and small on animal cells

Answer 6

Vacuoles

Question 7

Small, saclike structures that contain digestive enzymes

Answer 7

Lysosomes

Question 8

prepare certain protein compounds for dispersal from the cell.

Answer 8

Golgi Bodies

Question 9

-Small thin tubes
-act as support structures for the cell

Answer 9

Microtubules

Question 10

they serve as organizer structures for the microtubules within the cell. Can also be seen in animal cell

Answer 10

Centrioles

Question 11

Separates and protects the interior part of the cell from the outside environment

Answer 11

Cell membrane

Question 12

Act as supportive structure for plant cell

Answer 12

Cell wall

Question 13

Two kinds of organelles act as cellular powerhouses playing essential roles in manufacturing food and releasing energy, respectively

Answer 13

Mitochondria ( for animals) & Chloroplasts (for plants)

Question 14

organelles for the production of food in the form of sugars with the use of carbon dioxide, water and energy from sunlight

Answer 14

Chloroplasts

Question 15

the conversion of light energy into chemical energy that is stored in organic compounds such as carbohydrates/glucose.​

Answer 15

Photosynthesis

Question 16

Formula for photosynthesis

Answer 16

6CO(carbon dioxide) +6H2O (water) —->(With light) C6H12O6+ 6 O2

Question 17

Formula for Cellular Respiration

Answer 17

C6H12O6+ 6 O2 —-> 6CO+6H2O + ATP

Question 18

What are the three stages of Photosynthesis?

Answer 18

1.Capturing energy from sunlight​

2.Making ATP (Adenosine Triphosphate) and,​

3.Building carbohydrates​

Question 19

Conversion of chemical energy from nutrients (glucose) into ATP, and then release waste product

Answer 19

Cellular Respiration

Question 20

What are the three Stages of cellular respiration​?

Answer 20

1Glycolysis​

2Krebs Cycle​

3Electron transport chain​

Question 21

Its splitting glucose molecules into two molecules of pyruvate. It also produces two molecules of ATP and two molecules of NADH

Answer 21

Glycolysis​

Question 22

It occurs in inner mitochondrial membrane where series of protein complexes are located. This process produce large amount of ATP.

Answer 22

Electron transport chain​ & Chemiosmosis

Question 23

This process happens in the matrix of Mitochondria.
This process will produce:​

6 molecules of NADH​

2 molecules of ATP​

2 molecules of FADH2​

Answer 23

Krebs Cycle​

Question 24

The process by which living cells convert the energy released by the oxidation of organic compounds into the energy-carrier molecule ATP(Adenosine TriPhosphate).

Answer 24

Chemiosmosis
