The Chemistry of Photosynthesis
What are the two main stages of photosynthesis?
Light dependent reactions and the Calvin Cycle
What is first stage of cellular respiration that occurs in the cytoplasm and produces 2 net ATP.
Glycolysis
What is the organelle where photosynthesis occurs, but cellular respiration does not?
Chloroplasts
Stomata on plant leaves allow for the exchange of these two gases.
Oxygen and Carbon Dioxide
What organisms must consume other organisms for energy?
Heterotrophs
What high-energy molecule is produced during the light reactions and used in the Calvin Cycle?
ATP
What molecule is the final electron acceptor in the electron transport chain?
Oxygen (O2)
What is the term that describes organisms that produce their own food ?
Autotrophs
What gas is produced during cellular respiration and taken in by plants during photosynthesis?
Carbon Dioxide (CO2)
What is the name of the fluid-filled space inside the chloroplast where the Calvin Cycle takes place?
Stroma
Along with ATP, what molecule acts as an electron carrier in the light-dependent reactions?
NADPH
What cycle generates NADH and FADHâ‚‚ to fuel the electron transport chain?
The Krebs Cycle (Citric Acid Cycle)
What is the shared step between aerobic and anaerobic respiration?
Glycolysis
This structure in mitochondria creates the energy needed to form ATP by moving hydrogen ions.
Electron Transport Chain
What compound forms when pyruvate is converted in the absence of oxygen in muscles?
Lactic acid
What process uses a proton gradient across the thylakoid membrane to synthesize ATP?
Chemiosmosis
Each glucose molecules can produce up to this many ATP molecules through aerobic respiration?
36 to 38 ATP
Both photosynthesis and cellular respiration involve what electron carrier molecule?
NAD+/NADH
This form of energy from the sun is needed to start the process of photosynthesis.
Light energy
In photosynthesis, the light reactions take place in this specific part of the chloroplast.
Thylakoid membrane
What enzyme catalyzes the fixation of carbon dioxide during the Calvin Cycle?
RuBisCo
Before entering the Krebs cycle, what molecule is pyruvate converted into?
Acetyl-CoA
What are the two main products of photosynthesis that are reactants in cellular respiration?
What molecule stores chemical energy and is used by cells to power reactions?
ATP
What intermediate compound, derived from glucose, is produced during glycolysis and enters the Krebs cycle.
Pyruvate
