Biology Energy, Light And Photosynthesis

Front 1

What is the difference between NAD and NADP

Back 1

NAD is in Cell respiration, NADP is used in Photosynthesis

Front 2

What happens during the Krebs cycle

Back 2

Pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions. The pyruvic acid forms acetyl-coA when mixed with CoA. It combines with a 4-carbon compound to make citric acid. The citric acid circles around and the energy released from breaking and arranging bonds is captured as FADH2, NADH, and ATP.

Front 3

What does ATP Synhase do

Back 3

Allows Hydrogen protons through and spins ADP and combines them to make ATP

Front 4

Products of Glycolosis

Back 4

2 pyruvate acids, 2 molecules of NADH, and 4 molecules ( 2 net molecules) of ATP

Front 5

Equation of Cellular respiraation

Back 5

Oxygen+Glucose = co2 + water+energy (atp)

Front 6

Definition of cellular respiration

Back 6

The process that releases energy from food in the presence of oxygen.

Front 7

How does Cellular respiration maintain homeostasis?

Back 7

Controls the amount of co2, glucose, energy, etc that cells contain to keep a stable environment

Front 8

How many Calories in a grain of glucose

Back 8

4 Calories

Front 9

What's the % of energy contained in a glucose molecule that's captured in the bonds of ATP at the end of glycolysis?

Back 9

10%

Front 10

The 3 parts of an ATP Molecule

Back 10

3 phosphate groups, adenine, and ribose

Front 11

Why are the leaves of a plant green?

Back 11

Chlorophyll reflects green light

Front 12

Equation of photosynthesis

Back 12

carbon dioxide+water = sugars + oxygen

Front 13

What do plant pigments do in photosynthesis

Back 13

Capture light (chlorophyll is a pigment)

Front 14

What's the first process in light dependent reactions

Back 14

Light absorbtion

Front 15

How is ATP in the chloroplast membrane made

Back 15

With highly concentrated hydrogen ions

Front 16

What are CAM Plants

Back 16

CAM Plants are specialized to survive under hot, dry climates which would harm most other plants (Cactus)

Front 17

How does the Calvin cycle produce sugars? and what is the energy that makes it possible?

Back 17

With co2. The energy that makes it possible is ATP and NADPH

Front 18

Factors that affect the rate of Photosynthesis

Back 18

Co2 concentration, light, water, and temperature

Front 19

How is the structure of ATP make it an ideal source of energy for cells

Back 19

It can easily release/store energy by breaking and reforming the bonds between its phosphate groups

Front 20

What kind of light does chlorophyll not absorb well

Back 20

yellow light

Front 21

Where does light independent reactions occur and where does the Calvin Cycle occur

Back 21

Independent: Thylakoid
Calvin Cycle: Stroma

Front 22

WHat is photosystem II and I

Back 22

PHOTOSYSTEM 2: Electron Transport
Photosystem 1: Hydrogen Ion Movement and ATP formation

Front 23

How are P1 and Photosystem 2 dependent on each other

Back 23

Photosystem 1 relies on P2 to transport NADP and ADP over. P2 relies on P1 for ATP and NADPH to come over.

Front 24

WHat are the products of the Krebs cycle:

Back 24

NADH
FADH2
ATP
They all go to the ETC

Front 25

How does the ETC use the high-energy electrons from glycolysis and the Krebs Cycle?

Back 25

It take the ions, pushes them out to the intermembrane spae, and uses it to convert ADP to ATP

Front 26

Palisade Layer:
Spongy Layer:

Back 26

P: Absorbs light
S: Connects with stomata, has air pockets

Front 27

What happens in the electron transport chain

Back 27

The electrons are used to pump out hydrogen ions out of the inner mitochondrial compartment.
Hydrogens re-enter through a ATP Synthase that adds a phosphate to ADP and makes ATP
At the end of the chain electrons and hydrogen ions combine w/ oxygen to form water. (Oxygen is the final Acceptor of the elctrons)
