Which event occurs during the light-independent reactions (Calvin cycle) of photosynthesis?

• The chloroplast obtains energy and releases carbon dioxide and water

• The chloroplast captures light energy by generating ATP in the thylakoid membrane

• The chloroplast splits the water molecule and oxygen atoms are released

• The chloroplast uses the energy stored in ATP to make sugar from carbon dioxide

Which products are created during the light-dependent reaction of photosynthesis?

• glucose and carbon dioxide

• ATP and Oxygen

• starch and carbohydrates

• fructose and glucose

What do chloroplasts use to absorb solar energy?

• mitochondria

• carbon dioxide gas

• molecules of sugar

• the pigment of chlorophyll
