Final

Question 1

What is diffusion?

Answer 1

movement of particles from higher to lower concentrations

Question 2

what is the random movement displayed by microscopic particles suspended in fluid called?

Answer 2

brownian motion

Question 3

what osmosis?

Answer 3

diffusion of water across the semi permeable membrane

Question 4

what is facilitated diffusion?

Answer 4

molecules passing through protein channels

Question 5

what does passive transport mean?

Answer 5

diffusion that doesn’t required ATP

Question 6

awhat does active transport do and what does it require?

Answer 6

ATP is required, it moves molecules to low conservation to higher concentrations

Question 7

what is the difference between a solvent and a solute?

Answer 7

Solvent is the liquid and solute is the solid

Question 8

describe the difference between hypertonic and hypotonic solution?

Answer 8

hypertonic- higher solute concentration

hypotonic- low solute concentration

Question 9

what would happen is a hospital IV bag was pure water?

Answer 9

your blood cells would fill up w/water and burst

Question 10

what is a specifically happening to plants where they wilt?

Answer 10

the vacuole collapses

Question 11

what are the three components involved in a sexual reproduction?

Answer 11

meiosis, gametes, fertilization

Question 12

what is the main difference between sexual reproduction and asexual reproduction?

Question 13

what is a meiosis also known as?

Answer 13

reduction division

Question 14

what is the difference between diploid and haploid cells?

Answer 14

diploid has the full set of chromosomes

haploids half

Question 15

what crucial process happens in prophase 1 of meiosis and what is specifically happening?

Answer 15

chromosome crossingover, they’re exchanging genetic information

Question 16

clearly describe the difference between meiosis and mitosis?

Answer 16

mitosis has two identical cells, meiosis result in 4 genetically different cells

Question 17

where does fertilization always occur?

Answer 17

at the site of the egg

Question 18

fertilization results in the formation od the first diploid cell of anew organism. what is this cell called?

Answer 18

zygote

Question 19

what does ATP stand for?

Answer 19

adenosine tri-phosphate

Question 20

Draw a molecule of ATP

Answer 20

Question 21

What is the ultimate goal of cellular respiration?

Answer 21

ATP retrieval

Question 22

what’s the first stage of cellular respiration occurs in?

Answer 22

glycolysis, cytosol

Question 23

in what organism does this stage of cellular respiration occur in?

Answer 23

all of them

Question 24

in what organism does this stage of cellular respiration occurs ?

Answer 24

oxygen

Question 25

what is not needed for this stage of cellular respiration?

Answer 25

in the chloroplast, its a pigment

Question 26

Krab cycle

Answer 26

LOOK AT NOTES!!!

Question 27

Describe the difference between oxidation and reduction

Answer 27

o-lose electron | r-gain electrons

Question 28

describe both types of anerobic respiration

Answer 28

when oxygen is not available to be the final electron from the electron transport chain, the NADH created in glycolysis, reduces pyruvate to lactic acid and bacteria, animal cells or ethanol in yeast cells

Question 29

give two examples of both types of anerobic respiration

Answer 29

alcohol fermentation- beer and bread | Lactic fermentation- after workouts and yogurt

Question 30

what is the next stage in aerobic, cellular respiration and sometimes called the " transition stage'

Answer 30

oxidation of pyruvate

Question 31

where does this "transition stage" occur?

Answer 31

in the mitochondria matrix

Question 32

what is the starting substrate, the end product, and the by products of this " transmition stage"

Answer 32

pyruvate (start), acetol COA (end), 2NADH (Bypro)

Question 33

kreb cycle

Answer 33

Question 34

Write out the balanced reaction of Photosynthesis

Answer 34

6CO2 +6H2O-C6H12 +6O2

Question 35

Give me the long definition of photosynthesis

Question 36

What does photosynthesis occur in plant cells and what is chlorophyll?

Answer 36

in the chloroplast, its a pigment

Question 37

what are the first set of reactions of photosynthesis called and where do they occur?

Answer 37

the light dependent reaction, the thylakoid membrane

Question 38

what are the second set of reaction of photosynthesis called and where do they occur?

Answer 38

Light independent reaction thylakoid membrane

Question 39

what drives these reactions and what is the first one called that fixes the carbon from CO2 onto ribulose 1,5 bisphosphate?

Answer 39

RuBisCO

Question 40

what are the two goals of this second set of reactions of photosynthesis?

Answer 40

Production of glucose from CO2

Question 41

three components involved in sexual reproduction

Answer 41

meiosis, gametes, and fertilization

Question 42

what are the main differences between sexual and asexual reproduction?

Answer 42

sexual- two parents, genetically unique offspring | asexual- one parents, clones

Question 43

difference between sexual and asexual repro.

Answer 43

sexual- requires the 3 components and results in genetic variation in the offspring Asexual-alter or excludes one of the 3 component resulting in no genetic variation in the offspring
