For the following questions, choose one to discuss: chloroplast/photosynthesis State at the outset which one you will discuss.
A) What role do proton gradients play in the process of photosynthesis proton gradients allow
B) Where are proton gradients formed? Within what structures are they seen in chloroplasts How do the structures help them to maintain a gradient?
C) Explain where and how the chloroplast or mitochondria uses passive transport and active transport to complete photosynthesis or cellular respiration.
To understand photosynthesis, it is important to first understand the larger picture of what molecules the cell uses and generates and how the different molecules cycle between different reactions. The diagram shows a broad overview of the two stages of photosynthesis. Select the label that best corresponds to the lettered blanks in the diagram below.
The parentheses represent the choices for each label on the graph.
A. (ADP, ATP, O2, Co2)
B. (NADPH, Sugars, NADP+, Sunlight)
C. (H2O, Sugars, O2, Co2)
D. (Sugars, Co2, O2)
(c) Compare the differences between oxidative phosphorylation and photophosphorylation by
redrawing (if necessary) and completing the table given below:

- Look at the equation for photosynthesis and try to explain a basic overview of the process of photosynthesis. What is happening? What is being made and what is being used? Why is it important? In order to make one molecule of glucose, 2 G3P molecules are needed. In which step of the Calvin Cycle is the G3P made?arrow_forwardExplain how cellular respiration and photosynthesis are interrelated. (hint: there are three ways)arrow_forwardWrite the overall net reaction for photosyynthetic Co2 fixation. (Take into account both light and cark reaction of photosynthesis?)arrow_forward
- Draw a diagram of the dark phase of photosynthesis. You must represent this phase in the form of a cycle indicating the parts of carboxylation, reduction, generation of hexoses and regeneration.
