2.4 cell signalling to 2.6 photosynthesis

Question 1

first step of cellular respiration

Answer 1

glycolysis

Question 2

glycolysis

Answer 2

uses 2 atp, makes 4 atp, occurs in cytoplasm, anaerobic.

Question 3

reactants of glycolysis

Answer 3

CO2, NADH, ATP, FADH2

Question 4

products of glycolysis

Answer 4

4 ATP

Question 5

second step of cellular respiration

Answer 5

citric acid cycle

Question 6

citric acid cycle

Answer 6

occurs in mitochondrial matrix, chain of chemical reactions.

Question 7

final step of citric acid cycle

Answer 7

3 NADH and 1 FADH2 are used in oxidative phosphorylation, otherwise known as aerobic respiration. results in H20 and ATP

Question 8

final step of cellular respiration

Answer 8

electron transport chain ( + chemiosmosis)

Question 9

electron transport chain

Answer 9

collection of proteins bound to the inner mitochondrial matrix and organic molecules, electrons pass through in series of redox reactions; transfers electron donors to electron receptors. Couples this electron transfer with protein transfer.

Question 10

redox reactions

Answer 10

chemical reaction that takes place between an oxidizing substance and reducing substance

Question 11

photosynthesis equation

Answer 11

6CO2 + 6H2O into C6H12O6 + 6O2

Question 12

cellular respiration equation

Answer 12

C6H12O6 into 6CO2+CH20+ATP

Question 13

aerobic respiration

Answer 13

yes air

Question 14

anaerobic respiration

Answer 14

no air

Question 15

glycolysis function

Answer 15

glucose into 2 pyruvates

Question 16

krebs cycle function

Answer 16

releases stored energy - circular series of mitochondria reactions

Question 17

electron transport function

Answer 17

series of protein complexes that release energy. electrons enter the chain after being excited by light and energy is released in order to build carbs

Question 18

three steps of cell signaling

Answer 18

reception, transduction, response.

Question 19

receptor molecule

Answer 19

molecule that allows signal molecules to bind, such as protein found on surface of cell.

Question 20

ligand molecule

Answer 20

smaller, binds to larger. can be gas molecule, hydrophobic biomolecules (like lipids), hydrophilic biomolecules (certain proteins).

Question 21

chlorophyll

Answer 21

absorbs all light color but green - color you see is the color reflected - green

Question 22

carotene

Answer 22

orange/yellow/red
