Match each image with its label. Photosystem II ATP Granum Phospholipid Chlorophyll a Reset
The Correct Answer and Explanation is:
Here are the correct matches for each image and its label.
- Photosystem II: The image at the bottom left.
- ATP: The image at the top right.
- Granum: The image in the top middle.
- Phospholipid: The image in the bottom middle.
- Chlorophyll a: The image at the top left.
This matching exercise connects key components of photosynthesis with their visual representations. Each image depicts a specific molecule or structure vital to this process.
The image matched with ATP shows the chemical structure of Adenosine Triphosphate. It is clearly broken down into its three components: the adenine base, the ribose sugar, and the triphosphate group. ATP is the main energy currency for all cells, storing energy in its high energy phosphate bonds.
The image for a Granum accurately illustrates a stack of thylakoids. Thylakoids are membrane bound compartments inside chloroplasts. The light dependent reactions of photosynthesis occur within these structures. A stack of them is correctly called a granum.
The image for a Phospholipid shows a simplified model of the molecule, highlighting its distinct polar head and two nonpolar tails. These molecules are the primary components of biological membranes, including the thylakoid membrane, where they form a bilayer that houses protein complexes like photosystems.
The image correctly labeled as Photosystem II depicts a large protein complex embedded in a membrane. A key detail identifying it as Photosystem II is the depiction of a water molecule (H₂O) being split to release half of an oxygen molecule (½O₂). This process, known as photolysis, is unique to Photosystem II and is the initial step in the light dependent reactions.
Finally, the image for Chlorophyll a is a composite diagram. It illustrates the organizational hierarchy from a chloroplast down to the molecular level. Critically, it contains the detailed chemical structure of a chlorophyll molecule, the primary photosynthetic pigment responsible for absorbing light energy. This molecule is located within the photosystems and is essential for converting light energy into chemical energy
