The correct answer is signal transduction.
Signal transduction also called cell signaling refers to the conduction of molecular signals from the external of the cell to its internal. The signals perceived by the cells must be conducted efficiently into the cell to make sure an effective response. This step is stimulated by cell-surface receptors.
There are three phases in the procedure of communication or cell signaling, that is, reception, transduction, and response.
Answer:
The correct answer would be the active transport across the cell membrane.
The main functions of the cell membrane are a barrier, regulates transport (passive, facilitated, and active), the presence of receptors et cetera.
Only active transport (such as sodium pump, calcium pumps et cetera) requires the input of energy (ATP) for proper functioning. It uses energy to pump substances against the concentration gradient.
Thus, only active transport would be affected if less cellular energy is available.
