Verified step by step guidance1
Understand the structure of a chloroplast, which is the organelle where photosynthesis occurs in plant cells. It consists of several parts: the outer membrane, inner membrane, stroma, thylakoid membrane, and thylakoid space.
Recognize that the Calvin cycle is part of the photosynthesis process, specifically the light-independent reactions, which occur after the light-dependent reactions.
Identify the stroma as the fluid-filled space within the chloroplast, surrounded by the inner membrane, where the Calvin cycle takes place. This is where the enzymes necessary for the Calvin cycle are located.
Differentiate between the thylakoid membrane and thylakoid space. The thylakoid membrane is where the light-dependent reactions occur, while the thylakoid space is the area inside the thylakoid membrane.
Conclude that the Calvin cycle occurs in the stroma of the chloroplast, utilizing ATP and NADPH produced during the light-dependent reactions to convert carbon dioxide into glucose.
