Detailed explanation-1: -The three stages of cell communication (reception, transduction, and response) and how changes couls alter cellular responses. How a receptor protein recognizes signal molecules and starts transduction.

Detailed explanation-2: -Forms of signaling There are four basic categories of chemical signaling found in multicellular organisms: paracrine signaling, autocrine signaling, endocrine signaling, and signaling by direct contact.

Detailed explanation-3: -The signal transduction process links the signal molecule and the receptor protein to bring about a cellular response. 2. What are the 3 steps of signal transduction? Reception, Transduction, and Response are the three steps in the process of signal transduction.

Detailed explanation-4: -Definition. Protein translocation is a process by which proteins move between cellular compartments. Short amino-acid sequences within a protein, known as signal peptides or signal sequences, can direct its localisation, although translocation also occurs in the absence of these signal sequences.
