what is the photosynthesis equation?
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
in photosynthesis, what captures the light energy?
chlorophyll
what enters the light dependent reactions
6H2O
what exits the light dependent reactions
6O2
what is the first step in the light dependent reaction?
excites electrons in PS11 that causes it to the PS1
where is photosynthesis located?
chloroplast
where are the light dependent reactions located
thylakoid
what is the second step to LD reactions?
light energy splitting water molecules into H ions and oxygen
what carries electrons from PS11 to PS1
electron transport chain
in photosynthesis, where is the ETC located
thylakoid (ETC)
what is the third step of the light dependent reaction?
H moves to the NADP+ receivers and gets reduced to NADPH, which gets transported to the light independent reactions
what is created as a result of the ETC in LD
ATP
what from LD goes into the LID
ATP and NADPH
where is the LID reactions located
stroma
what is the first step of LID
carbon fixation
what is the second step of LID
reduction
what is the third step of LID
regeneration of RuBP
what occurs in glycolysis?
5C turns into 6C with rubp giving 1C
6C turn into two 3C
what occurs in reduction
NADPH reduces 3C into G3P with ATP providing the energy to do so
some G3P gets turned into glucose
what occurs in regeneration of RuBP
some G3P gets used to create more RuBP that will be giving to the carbon fixation part of LID
what enters the LID reactions
6CO2
what exits the LID reactions
glucose
what is the cellular respiration equation?
C6H12O6 + 6O2 → 6CO2 + 6H2O
where does cellular respiration occur?
mitochondria
what is the first step to cell resp
glycolysis
what is the second step to cell resp
oxidation of pyruvate
what is the third step to cell resp
krebs cycle / citric acid cycle
what is the fourth step of cell resp
oxidative phosphorylation
what is fermentation?
when there’s no oxygen (anaerobic conditions), it’s how we can produce NAD+ for glycolysis
where does glycolysis occur?
cytosol
what occurs in glycolysis? (3 things)
6C turns into 2 pyruvate of (3C)
2NAD+ turns into 2NADPH
2 ATP is used, but 4 ATP is produced (net of 2 ATP)
what enters glycolysis?
C6H12O2 (or 6C), 2 NAD+, 2 ATP
what exits glycolysis?
2 pyruvate, 2 NADH, 4 ATP
where does pyruvate oxidation occur?
in the mitochondrial
what occurs in pyruvate oxidation?
pyruvate gets oxidized to Acetyl CoA (2C) (hence the C in CO2 byproduct)
one atp is produced
one NAD+ is turned into NADH because of the oxidation
where does the krebs cycle occur?
mitochondrial matrix
what occurs in the krebs cycle?
acetyl CoA gets added to a 4C and the now 6C which is CO2
some redox happens here with NAD+ and FAD+ turning into NADH and FADH
One ATP is produced
what enters pyruvate oxidation
2 pyruvate, 1 nad+
what exits pyruvate oxidation
2 Acetyl CoA, 1 nadh, CO2
what enters the krebs cycle?
2 acetyl CoA, 3 NAD+, 1 FAD+, 1 ad pi
what exits the krebs cycle?
2CO2, 3 NADH, 1 FADH2, 1ATP
where does oxidative phosphorylation occur
inner membrane of the mitochondria
what occurs in oxidative phosphorylation
mass ATP production as electrons pass through the ETC/proton gradient
FADH2 and NADH bring their electrons and get oxidized and turned into electron acceptors FAD+ and NAD+
oxygen as the final electron acceptor
creates water as the byproduct
how much atp can be produced by oxidative phosphorylation at the max
34
how does the ETC (cell resp) generate ATP
the pumping of H ions from matrix to the intermembrane against the concentration (causes the proton gradient) changes the shape of ATP synthase, allowing it to produce ATP
what enters oxidative phosphorylation
6O2, electrons from the electron carriers (NADH, FADH2),
what exits oxidative phosphorylation
ATP
