The energy that powers living systems ultimately comes from the sun All eukaryotic organisms carry out respiration in the presence of O2 Plants provide the water and CO2 that animals need to carry out respiration All animals in some way rely on plants for their energy The energy that powers living systems ultimately comes from the sun All eukaryotic organisms carry out respiration in the presence of O2 Plants provide the water and CO2 that animals need to carry out respiration All animals in some way rely on plants for their energy ANSWER DOWNLOAD EXAMIANS APP
Photosynthesis and Respiration 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 ETS (electron transfer system in light reactions Photosystem II C4 pathway Calvin cycle ETS (electron transfer system in light reactions Photosystem II C4 pathway Calvin cycle ANSWER DOWNLOAD EXAMIANS APP

Photosynthesis and Respiration 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 NADPH to make new glucose O2 to make new H2O electron transport carriers to make O2 pyruvate to make ethanol NADPH to make new glucose O2 to make new H2O electron transport carriers to make O2 pyruvate to make ethanol ANSWER DOWNLOAD EXAMIANS APP
