Photosynthesis

Question 1

photosynthesis

Answer 1

method of converting solar energy into chemical energy stored in a carbohydrate

Question 2

All life depends on what chemical reaction

Answer 2

C6H12C6( glucose formula)

Question 3

Any living organism with chloroplasts can produce what

Answer 3

oxygen which comes from plants as waste

Question 4

What does chemical energy do for humans & comes from where

Answer 4

Natural gas formed from plants and animals that lived millions of years ago, provide heat and electricity

Question 5

Autotrophs

Answer 5

An organism that is ABLE to make its own food

Question 6

photoautotrophs

Answer 6

use sun energy to make organic compounds (like glucose) from light

Question 7

chemoautotrophs

Answer 7

use chemical energy (like hydrogen sulfide or methane) to make organic compounds

Question 8

chloroplasts

Answer 8

carbohydrate factories that use solar energy to form glucose which is used or converted into other forms

Question 9

synthesis reaction that requires energy

Answer 9

6CO2 (g) + 6H2O+ E - C6H 12O6 (s) + 6O2(g)

Question 10

Electromagnetic spectrum
low-high

Answer 10

Radio, microwave, infrared, visible energy (ROYGBIV), ultraviolet, x-ray, gamma

Question 11

pigment

Answer 11

chemical that absorbs light energy & gives an object its color

Question 12

Chlorophyll

Answer 12

found in most plants, does not absorb green light but reflects it

Question 13

Chlorophyll A

Answer 13

most abundant and most important in photosynthesis (bluish green pigment)

Question 14

Chlorophyll B

Answer 14

yellowish green pigment

Question 15

Chlorophyll C

Answer 15

found in brown algae

Question 16

Chlorophyll D

Answer 16

found in red algae

Question 17

Stack of pancakes

Answer 17

Grana

Question 18

Chocolate chips

Answer 18

chlorophyll

Question 19

pancake

Answer 19

thylakoid

Question 20

syrup

Answer 20

stroma

Question 21

links

Answer 21

lamellae

Question 22

outer membrane of chloroplast

Answer 22

separates the chloroplast from the rest of the cell

Question 23

inner membrane chloroplast

Answer 23

regulates the diffusion of necessary materials in & out of the chloroplast (H2O, CO2, O2) and increases the amount of surface area for more photosynthesis

Question 24

Leaf function & structure

Answer 24

most photosynthesis occurs, stomata on bottom due to sunlight

Question 25

stomata

Answer 25

serve as channels and allow gases to diffuse in & out of leaf and allow water to pass

Question 26

Why do leaves change color in autumn

Answer 26

they contain pigments carotene and xanthophyll(yellow) and when sun isn't as intense, the chlorophyll doesn't mask the other pigments and begins to break down, allowing other pigments to show

Question 27

Energy carrier

Answer 27

ATP (ADP+E+P)

Question 28

Electron carriers

Answer 28

NADHP & FADH

Question 29

how many glucose molecules can be produced during photosynthesis each second?

Answer 29

thousands

Question 30

The light Reaction

Answer 30

-Light dependant -takes place in grana +requires light + chlorophyll

Question 31

Glycolysis

Answer 31

series of reactions in the cytoplasm which breaks 6C glucose into 3C pyruvate, and makes ATP and NADHP to be used in e-transport chain

Question 32

Kreb Cycle

Answer 32

breaks pyruvate down further in the mitochondria, produces electron carriers NADPH + FADH2, + releases CO2 as a waste product

Question 33

Electron transport train

Answer 33

uses O2 as final e- acceptor to produce ATP + release water as a waste product

Question 34

Fermentation

Answer 34

"anaerobic cellular respiration", part degreation of glucose when O2 not present, allows lactic acid to happen due to glycolysis continuing, forms 2 ATP

Question 35

heterotrophs

Answer 35

unable to produce their own food bc lacking chloropyll, takes in energy through outside sources

Question 36

Cellular Respiration

Answer 36

process eukaryotes use to break down carbohydrates + carbon molecules to make ATP when O2 is present

Question 37

How do we maintain our body temp?

Answer 37

as we digest food + break bonds, some E is used for work and some is released as heat

Question 38

Plants undergo both:

Answer 38

Photosynthesis, Cellular Respiration

Question 39

Chemical reaction for Photosynthesis

Answer 39

6CO2 + 6H2O + E--C6H12O6+ 6O2

Question 40

Chemical Reaction for Cellular Respiration

Answer 40

C6H12O6 + CO6 -- 6CO2 + 6H2O --E

Question 41

why do plants close their stomata

Answer 41

to prevent water loss when conditions are hot or dry

Question 42

C3 plants

Answer 42

go through Calvin cycle 3 times + produce half glucose

Question 43

C4 plants

Answer 43

go through Calvin Cycle 4 times + produce C4 molecules to release in a leaf for use of stomata, allows plants to grow in intense conditions
