Flashcards in Unit 1B - Photosynthesis & Cellular Respiration Deck (28):
1

The starting molecule for glycolysis is

Glucose

2

The Kreb's Cycle is also known as the

Citric Acid Cycle

3

Glycolysis makes a total of _____ be has a net gain of ____ ATP

4 total

2 net gain

4

The overall purpose of the ETC is to

produce ATP 

5

The overall yield of cellular respiration with oxygen is ______ ATP

36

6

For 1 molecule of glucose, how many molecules of ATP are produced with oxygen?

Without oxygen?

36

2

7

How do the products of cellular respiration relate to photosynthesis?

The products of cellular respiration (water and carbon dioxide) are the reactants of photosynthesis

8

Most of the energy generated by aerobic respiration is made during the 

Electron Transport Chain

9

When a cell is running low on oxygen it will begin to do

Fermentation

10

Which organisms do each type of fermentation?

Lactic Acid - animals, some fungi, bacteria

 

Alcoholic - yeast

11

List the products of each type of fermentation

Lactic Acid - lactic acid & NAD+

 

Alcoholic - alcohol, CO2, and NAD+

12

When is energy released from an ATP molecule?

When the bond is broken between the second and third phosphate

13

List the correct sequence of events for cellular respiration (aerobic and anaerobic)

Aerobic - 

Glycolysis --> Kreb's --> ETC

 

Anaerobic -

Glycolysis --> Fermentation

14

The general formula for cellular respiration is

C6H12O6 + 6O2 --> 6CO2 + 6H2O + 36ATP

15

The cause of muscle soreness is

Buildup of lactic acid from lactic acid fermentation

16

Which organisms carry out cellular respiration?

All eukaryotic organisms

 

(Only things that don't are anaerobic)

17

The two steps of photosynthesis are

Light Dependent and Light Independent (Calvin Cycle)

18

Chlorophyll is found 

In the thylakoids

19

A stack or stacks of thylakoids is called

Grana (granum)

20

Plants take in _____ and give off _____

Carbon Dioxide; Oxygen

21

The overall equation for photosynthesis is

6CO2 + 6H2O + Light Energy --> C6H12O6 + 6O2

22

C6H12O6 is the chemical symbol for

Glucose

23

What kind of biomolecule is glucose?

Carbohydrate (sugar)

24

The light-collecting molecules found in plants are called

Pigments

25

The pigment most commonly found in plants is

Chlorophyll

26

Why do plants appear green?

They do not absorb green light

 

They reflect green light

27

The three things that affect the rate of photosynthesis are

1. temperature

2. light intensity

3. amount of water

28

What are the overall purposes of photosynthesis and cellular respiration?

Photosynthesis - energy capture (makes chemical energy in the form of glucose)

 

Cellular Respiration - energy release (breaks down the chemical energy stored in glucose and creates energy in the form of ATP which the cell can use)
