Concept explainers
To compare: The sketch diagrams illustrating a proton gradient involved in the chloroplast and mitochondria.
Introduction: Photosynthesis is a process by which carbon dioxide and water are used to produce glucose molecules using energy from sunlight. During this process, oxygen gas is evolved. Reactions of photosynthesis take place in the chloroplast of the plant cell that contains the green pigment chlorophyll.
To determine: Whether, in each sketch, the protons are being pumped into the inner most compartment or out of it.
Introduction: Photosynthesis is a process by which carbon dioxide and water are used to produce glucose molecules by using energy from sunlight. During this process, oxygen gas is evolved. The several reactions of the photosynthesis take place in the chloroplast of the plant cell that contains the green pigment chlorophyll.
To determine: Whether the direction of proton gradient matters in the chloroplast and mitochondria.

- Explain the role of photosynthetic pigments in harnessingsolar energy.arrow_forwardGive typing answer with explanation and conclusion A biologist is measuring photosynthesis and respiration in a lake. She places a pair of bottles in the lake and measures the initial oxygen concentration to be 9.56 mg O2/L. Twenty-four hours later, she measured the oxygen concentrations in the light and dark bottles: 8.23 mg O2/L in the dark bottle and 10.11 mg O2/L in the light bottle. Calculate the hourly rates of NPP and respiration for this ecosystem. Be sure the units are correct. A) NPP=0.0229 mg O2/L/h, R=0.0554 mgO2/L/h B) NPP=.55 mgO2/L/h, R=1.33 mgO2/L/h C) NPP=-0.0554 mgO2/L/h, R= -0.0229 mgO2/L/h D) NPP=0.0229 mg O2/L, R=0.0554 mgO2/Larrow_forwardExplain how electrons from water can be used to produce both ATP and NADPH.arrow_forward
