QuestionAnswer
Organisms that build organic molecules from inorganic compounds autotrophs
organisms that obtain organic molecules by eating other organisms or their by-products heterotrophs
making of atp by using energy from H+ gradient - includes chemiosmosis and oxidative phosphorylation chemiosmosis
series of enzymatically catalyzed reactions ex. cellular respiration biochemical pathways
reactions not requiring oxygen anaerobic
reactions requiring oxygen aerobic
protein complex in the christae, makes atp from adp and pi atp synthase
occurs by all organisms in the mitochondria - energy comes from food indirectly making ATP oxidative phosphorylation
nadh produce how many atp 3
fadh2 produce how many atp 2
is more energy made through substrate level or chemiosmosis chemiosmosis
what is the balanced equation for cellular respiration c6h12o6 ----> 6co2+6h2o+36atp
which phosphorylation includes photophosphorylation and oxidative phos? chemiosmosis
phosphorylated substrate will catabolize to release the phosphate substrate level phos
where does glycolysis take place cytosol

what is the reactant and product for glycolysis glucose: pyruvate, ATP and NADH
what is the reactant and product for oxidation of pyruvate pyruvate: co2, NADH, acetyl
what is the reactant and product for citric acid cycle acetyl: NADH, FADH2, ATP and CO2
if a reaction is aerobic where does it occur? mitochondria
how does oxidative phosphorylation take place? collects products of other stages and converts to ADP
which cycle produces the most ATP? Citric acid cycle
How many gross and net ATPs are produced by total oxidation of one mole of glucose? 38 and 36

the hydrolysis of one adp to atp + phosphate will require how many kcal 7.3
the inner folded membrane is where what takes place oxidative phosphorylation
what is produced in the matrix co2
why dont you oxidize every molecule of food that is ingested some are to provide raw materials for others
in cellular respiration what is the final electron acceptor in the etc and what is formed? oxygen and water
balanced equation for photosynthesis 6co2+12h2o+light ----> c6h12o6+6o2+6h2o
an organism, obtaining energy from sunlight as its source of energy to convert inorganic materials into organic materials for use in cellular functions photoautotrophs
pigment disorder, cannot repair uv damage Xeroderma pigmentosum
range of all possible frequencies of radiation electromagnetic spectrum
particle of light photon
shorter wavelengths = higher energy
longer wavelenths= lower energy
