Term
What is the equation for photosynthesis?
Definition
12H2O + 6CO2 --Light~Chloryphyll--> 6O2 + C6H12O6 + 6H2O
Term
Light dependent reaction
Definition
Required:Light, water, NADP, Chlorophyll

Produced:ATP, NADPH, O2
Term
Light Independent reaction
Definition
Required:CO2, ATP, NADPH, RUBP

Produced: Sugar, RUBP
Term
light use light to make?
Definition
ATP and NADPH
Term
What is made in the light reactions that is used in light independant?
Definition
ATP, NADP, NADPH
Term
What is the role of water in photosynthesis?
Definition
source of hydrogen, electrons for chlorophyll
Term
How are C4 plants different from C3 plants?
Definition
C4 plants adopted to hot dry climates, have PEP(grabs CO2), RUBP
Term
Light reactions happen where?
Definition
In the Thylakoid, sugar is made in the stroma.
Term
what happens in the Light dependent reactions?
Definition
1)Light excites elcctrons in chlorophyll, they jump up and are grabbed by electron acceptor molecules and passed to enzymes - then energy is used to make ATP

2)Water is split using light(photolysis) to replace electrons chlorophyll has lost

H2O-->NADP ->NADPH`+2H'ions + O
Term
Glycolisis
Definition
1)Glucose -->2 Molecules of pyruvate Takes place in the cytoplasm.
2)no co2 required
3)takes 2 ATP to start reaction
Term
NAD and FAD
Definition
coenzymes/hydrogen transport molecules
Term
Role of O2
Definition
oxygen picks up the electrons at the end of the electron transport chain it is the final electron acceptor.
o2->o+o...o2->1/2 o2...o+2e->o
Term
Cell respiration
Definition
cytoplasm { 1)Glycolysis
Mitochandria:{2)Citric acid cycle
{3)Electron transport chain
Term
2)Citric Acid Cycle
Definition
Produces 2 Atp
-CO2 released
-NAD + H->NADH
-FAD + 2H->FADH2
Term
Electron transport chain and chemiosmosos
Definition
-NADH & FADH drop off H atoms to enzymes on electron transport chain
-The enzymes pass the electrons chain to other enzymes but kick the outer protons out to the outer compartment of mitochandria
-the H ion start to diffuse back to the inner compartment through a protein channel that makes ATP using the energy of the H+ diffusion
Term
what part of aerobic cell respiration makes the most ATP?
Definition
electron transport chain and chemiosmosis
Term
what part of cell respiration requires no oxygen?
Definition
glycolysis
Term
what is the role of oxygen in cell respiration?
Definition
oxygen picks up the electrons at the end of the electron transport chain and its the "final electron acceptor"
Term
what is the equation for aerobic cell respiration?
Definition
C6H12O6 + 6O2-> 6CO2 + 6H2O
Term
how does ATP get made during the electron transport chain?
Definition
H+ diffuse across inner membrane of mitochondria through a protein channel(ATP Synthase) which makes ATP
Term
How does a CAM plant do photosynthesis differently from other plants
Definition
open stomata and take in CO2 at night, and store it as an acid
Term
During glycolysis, what is made by your cells if they are low in oxygen?
Definition
lactic acid
Term
What is made by yeast cells during anerobic respiration? How many ATP are made?
Definition
Ethonal + CO2
-2 ATP
Term
Endotherm
Definition
inside heat, heat from aerobic cell respiration used to heat body
Term
ectotherm
Definition
outside heat, environment determines body temp
Term
Anerobic respiration
Definition
-Without oxygen
-lactic acid fermentaion
-2 atp from glucose
Term
yeast
Definition
Alcoholic fermentation
-Glucose->ethonal + CO2 +2ATP
Term
Xylem
Definition
H2O
-dead tissue
Term
phloem
Definition
FOOD
-living tissue
Term
movement of food
Definition
sugar is actively pumped into phloem, atp required
Term
the movement of water through a plant
Definition
root hairs, water moves in osmotically
-transpiration
-cohesion
Term
Pistil (Female)carpel
Definition
Stigma, style, ovary
Term
recepticle
Definition
support
Term
sepal
Definition
protects flower bud
Term
stamen (Male)
Definition
Anther, Filament
Term
anther
Definition
pollen made here
Term
stigma
Definition
pollen sticks here
Term
ovary
Definition
protects developing seed
Term
ovule
Definition
seed within ovary, immature seed
