26. We placed some Chlamydomonas cells in a CO2 analyzer and generated the light responsecurve shown here.Which statement(s) accurately describe what is going on in the cells at the portion of the curveindicated by the arrow.1. Phosphoglycerate (PGA) is being reduced to G3P.2. Taking into account respiration, the rate at whichCO2 is being fixed by the Calvin Cycle is actuallyonly 40.3. The rate of photosynthesis is likely limited by theamount of CO2.4. The rate of photosynthesis equals the rate ofrespiration.A. 1, 2 and 3B. 1 and 3C. 2 and 4D. 4 onlyE. All of 1, 2, 3 and 4 are correct

Which process is found in both cellular respiration and in the light reactions of photosynthesis?Calvin cycleglycolysiselectron transport chaincitric acid cycle

Looking back at the figure above; recall that the curve integrates both cellular respiration andphotosynthesis and that the rate of respiration is constant, regardless of the light intensity.At a light intensity of 200, what is the rate that CO2 is actually being consumed by the CalvinCycle?A. 20B. 25C. 40D. 55E. 156

Photosynthesis and Cellular Respiration Diagram

Evidence indicates that phototaxis is linked to the overall energy state of the Chlamydomonascell. When the energy state of the cell is low it moves towards light; when it is high, it movesaway from light.Which of the following situations would result in a cell exhibiting positive phototaxis?A. High levels of NAD+ compared to NADH in the cytosol.B. High levels of ATP compared to ADP in the chloroplast stroma.C. High levels of glucose in the mitochondrial matrix.D. High levels of lactate in the cytoso

In which part of chloroplast light reaction of photosynthesis occurs ?
