The correct options are C, D, and E.
Explicação
## Step 1<br />The light-dependent reactions of photosynthesis are the first stage of photosynthesis. They occur in the thylakoid membranes of the chloroplasts. During these reactions, light energy is captured and used to produce ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These are energy carriers that are used in the next stage of photosynthesis, the light-independent reactions.<br /><br />## Step 2<br />The light-dependent reactions also release oxygen gas as a waste product. This is because water molecules are split to provide electrons for the light-dependent reactions. The oxygen produced is released into the atmosphere.<br /><br />## Step 3<br />The light-dependent reactions do not use carbon dioxide to produce glucose. This is a process that occurs in the light-independent reactions, also known as the Calvin cycle, which uses the ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.<br /><br />## Step 4<br />The light-dependent reactions do not occur in the stroma of the chloroplast. The stroma is the fluid-filled space outside the thylakoid membranes where the light-independent reactions occur.
