when we look at a leaf, we see the colors of light that are reflected off its surface. how does the relatively low flow of oxygen in green light?
Answer:
Usually, the color of leaves is green as they contain chlorophyll and it's reflecting the color of chlorophyll but when we look at a leaf, we see the colors of light that are reflected off its surface because chlorophyll in plants gives the leaf its color. The chlorophyll can't absorb oxygen, that is why it causes a reduction in the flow of oxygen and therefore the chlorophyll is green and reflects off green light.

Answer: Receptor
Explanation: a protein that detects a signal molecule and performs an action in response.
A receptor protein is a type of protein that detects a signal molecule (ligand) and performs an action in response. It can induce a chemical reaction within the cell or initiate a signaling pathway which can change the cell's behaviour.
A protein that detects a signal molecule and performs an action in response is called a receptor protein. Receptor proteins in or on a target cell bind to specific molecules outside the cell called ligands. When a ligand binds to its specific receptor, it induces a chemical reaction within the cell. This binding could open a channel for certain ions to flow into the cell or initiate a signaling cascade or pathway with the help of second messengers, enzymes, and other proteins. The signaling cascade eventually leads to a change in the cell's environment or behavior. For example, neurotransmitters such as dopamine can act as ligands, binding to dopamine receptor proteins on nerve cells and causing specific responses in these cells.
