Chapter 5
Multiple Choice 1. The plants need ATP as energy to realize the photosynthesis. 2. Photosynthesis is an example of an exergonic; light energy is captured by pigment molecule chemical reaction because endergonic; the reactions occur inside a cell. 3. The evolution of photosynthesis resulted in an increase in the amount of O2 in the atmosphere. 4. A plan appears green because it contains chloroplasts and the chlorophyll a absorbs ultraviolet light. 5. The organisms would use a red color of light. 6. The part of the chloroplast associated with the production of carbohydrates the thylakoid 7. The ATP by the cell to move electron through the electron transport chain. 8. There is carbon fixation at night if there is a source of ATP and NADPH. 9. During photorespiration the enzyme’s active site binds to O2 instead of CO2. 10. A C4 plant is the plant that only opens its stomata at nights.
Write It Out 1. Knowing that the photosynthesis produce oxygen, the Photosynthesis affect a meat-eating animal since the meat eater prey on the plants eater therefore provide them with some oxygen. 2. If plants absorbed all wavelengths of visible light, they would appear black because there would be no light reflect. 3. Thylakoid membrane is bound compartment inside chloroplasts and cyanobacteria. Then the Chloroplast is a plastid that contains chlorophyll and in which photosynthesis takes place. Next is the reaction center which is a complex of several proteins, pigments and other co-factors assembled together to execute the primary energy conversion reactions, followed by the photosystem which is the pigment molecules organized into photosystems capture sunlight in the chloroplast. Then the electron transport chain is a sequence of biochemical reduction–oxidation reactions that affects the transfer of electrons through a series of carriers. 4. All the following molecule are involved either in the light reactions or carbon reaction: 1st, O2 after the light reactions, CO2 is obtain from a carbon reaction, Carbohydrates cannot be obtain without carbon reaction, chlorophyll a absorbs most energy from wavelengths of violet-blue and orange-red light, photons are the energy input used for light reactions, NADPH intervene in the last step of the electron chain of the light reactions of photosynthesis, but also in the diminishing of CO2 in a carbon reaction, ATP is an important enzyme that provides energy for the cell in the light reaction. H2O provides electrons for light-dependent reactions. 5. The light reactions of cyclic photophosphorylation would produce ATP 6. Cyanobacteria gave rise to the chloroplasts of today’s plants and algae because cyanobacteria are the source of pigment and the chlorophyll a in the most important pigment in the photosynthesis. 7. The actual source of the added biomass is obtained from the presence of carbon on a plant. (Undone) 8. The Biological basis for this observation is called the photosynthesis where the plant produces Oxygen for the mouse to survive. 9. The 18O would end in the Glucose molecule because it was used in the CO2 in a carbon reaction. 10. In a photorespiration O2 is absorbed and CO2 is rejected, on the other hand, in
