bio three Flashcards
cell respiration
- glycolysis: break down of glucose in cytosol
- transition rxn: exergonic 3C-2C
- kreb cycle: glucose all broken down
- etc
glycolysis
cytosol
2ATP
2NADH
2ATP to hydrolysize phorphirilization glucose to split 3C, phorprilization
loses H and gain another phosphate group
pyruvate
transition rxn
matrix
2NADH
x2
pyruvate loses CO2= 2C n loses H
acetyl coenzymeA
kreb’s cycle
matrix
2ATP
6NADH
2FADH
x2 COA falls off releases energy to form bond btw oxaloacetate 4C + citric Acid 6C 2CO2 falls off 4H falles off becomes oxaloacetate 4C
ETC
34ATP
10NADH=H falls off. H=electron&proton.
-electron goes to cytochromes. movement powers pump that move H+ into intermembrane space
H+ fadiff throuh atp synthase (oxidative phorphorilization)
Oxygen: final electron acceptor, move e- from cytosome, water formed
fadh
2ATP
nadh
3atp
chemiosmosis
the movement of ions across a selectively permeable membrane, down their electrochemical gradient.
anaerobic respiration
muscle cell&bactieria
glycologist: 2pyruvate. 2 atp formed,
- pyruvate steals H from NADH=;actic acid: fadiff out off cell
- ethanol: CO2 out
Light rxn
thylakoid
photosystem2 (protein that hlds pigment)gets recieves proton-Primary electron acceptor-cytochromes to produce energy that powers pump pushes H+ into thylakoid. movement of e- produces NADPH’Atp. cytochromes to ps1 n into the stoma combines with H+ n taken by NADPH
H+ inside thylaoid to outside ATP synthese
cylical electron flow
e- into the stoma goes back to PEA to ^ amt of ATP
phtolysis
H20 split into OnH, oxygen pair up: O2
hydrogen into electron and proton
photosystem
pigement absorbs light energy and move causing molecules to vibrte, potential energy^, e- escape orbit: molecules loose electron to PEA: redox rxm
dark rxn/calvin rxn
stoma
6NADP
(x2) 3 rubisco
1 carbon fixated onto RuBP by Rubisco enzyme, then split into2 3c
phosphate and H+ added to each, called 6 G3p
1 g3p half a glucose leaves cycle, 5 stays to form 3 RuBP
rubisco
6 active sites
3: RuBP
3: co2
dark rxn
18 atp ised
rubsico mistake
photorepspiration
attaches to 02 not co2 creates 5c ! plan’t succesful
prevention: stoma is plugged
homrone
- reception
- signal transduction
- cellular response
regulation of respiration
glycologyist: phsphotrutokinace enzyme add phosphae to sugar n break it down. ATP allosteric inhibitor to it
fat metabolism
fat broken down into 2 carbon section n go into kreb (acytol
mesophil
cells in middle of leaves that contain choroplst.
top layer is tightly packed, not bottom
repsiration
sugar get oxidize
exergoniv
phtotosynthesis
water get oxidize
endergonic
stoma=02
stomata: co2
cam plants
goal: infrease influx of c02
arid
opens stoma at night: don’t loose water
take co2 to CAM metabolism n break cruselacean acid back to c02 when daylight (does photosynthesis then) bc equilibrium
