Most solutes that are reabsorbed in the proximal convoluted tubule use which of the following pathways? a) transcellular b) paracellular.

Transcellular.

Explanation:

The transportation of solutes and water occurs in the proximal convoluted tubule. The transport of solute occurs mainly via the two routes of transport known as paracellular transport and transcellular transport.

Transcellular transport may be defined as the transport by the cell through the cell. This process requires the energy for the transportation of molecules across the cells. The solutes are transported through the cell and most common route of transfer present in the proximal convoluted tubule.

Thus, the correct answer is option (a).

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse
