The rate of photorespiration in most plants increases at.higher temperatures. Some plants have evolved a somewhat round-about system to deal with this problem. This series of reactions is called Calvin cycle C4 pathway ETS (electron transfer system in light reactions Photosystem II TRUE ANSWER : ? YOUR ANSWER : ?
Carbon fixation requires the expenditure of ATP molecules which is generated by ETS (electron transfer system) during the light reactions formation of glucose during the Calvin cycle None of these replenishment of chlorophyll TRUE ANSWER : ? YOUR ANSWER : ?
Which enzyme is involved in carbon-fixation reaction? NADP reductase Ribulose bisphosphate carboxylase Cytochrome reductase Glycerol kinase TRUE ANSWER : ? YOUR ANSWER : ?
Assume the combined processes of photosynthesis and cellular respiration, the electrons that start as part of H2O at the beginning of the light reactions end up attaching to electron transport carriers to make O2 NADPH to make new glucose O2 to make new H2O pyruvate to make ethanol TRUE ANSWER : ? YOUR ANSWER : ?
In cells having organelles, the steps of the Krebs cycle and the electron transport system occur in the mitochondria none of these cell membrane endoplasmic reticulum TRUE ANSWER : ? YOUR ANSWER : ?
