<h2>
Liver cell Vs Nerve cell</h2>
Explanation:
- b. liver cells can reproduce while the nerve cells cannot.
Liver cells , the fundamental units of liver are called hepatocytes. Hepatocytes secrete bile that helps in digestion by emulsifying fats. Hepatocytes are capable of dividing and they can regenerate damaged parts of the liver.
In contrast,
Nerve cells, the fundamental unit of nervous system are neurons. Neurons are longest cell of the human body and they contain a cell body and a long axon. Neurons conduct nerve impulses. Neurons are incapable of dividing and hence once damaged neuron cannot be replaced.
Answer:
D
Explanation:
Hormones are bigger than the cell pores hence cannot pass through the cell membrane to influence biochemical processes. Therefore, hormones (such as glucagon and insulin) bind onto receptors on the cell membrane, then transmembrane proteins, such as the G-protein, change conformation activating the secondary messengers inside of the cell. Cyclic- AMP is a major secondary messenger significant in activating protein kinases.
Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility.
