Answer;
The mismatched pair is;
C) receptor proteins — bind with enzymes
Explanation;
- A receptor protein is a protein molecule that receives chemical signals from outside a cell. When such chemical signals bind to a receptor, they cause some form of cellular/tissue response, e.g. a change in the electrical activity of a cell.
-They are generally trans-membrane proteins, which bind to signaling molecules outside the cell and subsequently transmit the signal through a sequence of molecular switches to internal signaling pathways. There are two types of receptors: internal receptors and cell-surface receptors.
Answer/Explanation:
Using solar energy, photosynthesis uses carbon dioxide and water to produce glucose and oxygen, whereas respiration uses glucose and oxygen to produce energy, releasing carbon dioxide and water.
Therefore, photosynthesis and respiration act as a cycle, using reverse reactants and products.
Photosynthesis builds food for the cell to use, respiration uses this food to power cellular processes.
Answer:
A. The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell
