Both photosynthesis and respiration occur in leaves when they are in the light. If the leaves float, is more O2 being produced by photosynthesis or consumed by respiration?

Choose the CORRECT order of reactions that are conducted by photosystem I. P700 is activated by two photons → two Chl A0 accept two high-energy electrons → one quinone A1 is fully reduced → two electrons are passed on one 4Fe–4S cluster → two molecules of ferredoxin are reduced → ferredoxin–NADP+ reductase takes two protons from the stroma and reduces one NADP+ P680 is activated by two photons → two Chl A0 accept two high-energy electrons → two molecules of ferredoxin are reduced → ferredoxin–NADP+ reductase oxidizes one ferredoxin at a time to reduce FAD to FADH- and then to FADH2 → the proton-motive force is created P700 is activated by a photon → Chl A0 accepts two high-energy electrons → one plastoquinone QA is fully reduced → two electrons are passed on one 4Fe–4S cluster → two molecules of ferredoxin are reduced → ferredoxin–NADP+ reductase takes two protons from the stroma and reduces one FAD P700 is activated by a photon → pheophytin accepts two high-energy electrons →…

How are the processes of cellular respiration and photosynthesis related? The carbon molecules in glucose are converted to what molecule during respiration? What happens to the carbon dioxide molecules plants use in photosynthesis? Do plants have both chloroplasts and mitochondria? Why would this be?

What are the overall inputs (substrates and energy sources) and outputs (products and by- products) for the light-capturing reactions of photosynthesis and the Calvin cycle reactions of photosynthesis?
