Chap 6 terminology

Question 1

Chlorophyll

Answer 1

light absorbing green pigment that begins photosynthesis

Question 2

Chloroplast

Answer 2

membrane bound organelle in green plant and agal cells that carries out photosynthesis

Question 3

Stroma

Answer 3

2 membranes of chloraplasts; inner membrane and outer membrane encolsed in the stroma

Question 4

Thylakoid

Answer 4

membrane bound sacks inside the stroma

Question 5

Grana

Answer 5

colums of stacked thylakoids

Question 6

Lamelle

Answer 6

groups of unstacked thylakoids between grana

Question 7

Thylakoid membrane

Answer 7

photosynthetic membrane containing light gathering pigments molecules and electron transport chains

Question 8

Thylakoid lumen

Answer 8

fluid filled space inside a thylakoid

Question 9

Glucose

Answer 9

end product of photosynthesis

Question 10

ATP (Adenosine Triphosphate)

Answer 10

molecule containing 3 high energy phosphate bonds that acts as the primary energy transferring molecule in living organisms

Question 11

ADP

Answer 11

molecule containing 2 high energy phosphate bonds that may be formed by breaking one of the phosphate bonds in ATP

Question 12

NADP+

Answer 12

accepts one H+ atom and two electrons then converted into NADPH; and electron acceptor

Question 12

NADPH

Answer 12

donates one H+ atome and two electrons then converted into NADP+ I an electron donor

Question 13

Light dependant reaction

Answer 13

first step of reactions in photosynthesis ( stage 1&2). Light energy excites electrons in chlorophyll molecules, power chemiosmotic ATP synthesis and results in th reduction of NADP+ to NADPH

Question 14

Light Independant reaction

Answer 14

last set of reactions ( stage 3) in photosynthesis ( the Calving cycle) these reactions do not require solar energy

Question 15

Carbon Fixation

Answer 15

process of incorporating CO2 into Carbohydrate molecule

Question 16

Photosystem

Answer 16

Chlorophyll and other pigments are arranged in the thylakoid membrane.

Question 17

Electron Transport Chain

Answer 17

Process of removing excited electron from the photosystem and passing it from one molecule to another in a sequence of steps.

Question 18

Photolysis

Answer 18

chemical reaction in which a compound is broken down by light; in photosynthesis water molecules are split by photolysis.

Question 19

Oxidation

Answer 19

reaction in which an atom or molecule loss electrons

Question 20

Reduction

Answer 20

reaction in which an atom or molecule gains electrons

Question 21

Chemiosmosis

Answer 21

process of making ATP using the energy from an H+ ion concentration gradient.

Question 22

Oxidation

Answer 22

Reaction in which an atoms or molecule loses electrons

Question 23

Reduction

Answer 23

A reaction in which an atom or molecule gains electron

Question 24

Chemiosmosis

Answer 24

Process of making ATP us8ng the energy from an H+ ion concentration gradient

Question 25

What is a photon?

Answer 25

A pocket of light

Question 26

What is photosynthesis

Answer 26

The process by which green plants and other organisms uses solar energy , carbon dioxide and water to produce carbohydrates
