## Step 1<br />Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This process produces glucose and oxygen as byproducts.<br /><br />## Step 2<br />The reactants of photosynthesis are carbon dioxide and water. These are the substances that are consumed during the process to produce glucose and oxygen.<br /><br />## Step 3<br />The light-dependent reactions of photosynthesis occur in the thylakoid membranes of the chloroplasts. These reactions require light to produce ATP and NADPH.<br /><br />## Step 4<br />The light-dependent reactions produce ATP and NADPH, which are used in the Calvin cycle to produce glucose.<br /><br />## Step 5<br />The Calvin cycle takes place in the stroma of the chloroplasts. This is where the ATP and NADPH produced in the light-dependent reactions are used to produce glucose.<br /><br />## Step 6<br />The main product of the Calvin cycle is glucose. This is the molecule that is produced from the ATP and NADPH generated in the light-dependent reactions.
