Assume that cellular uptake rates and drug delivery rates of compounds 1 and 2 are identical. If the proposed mechanism of sensitization by Compound 1 is correct, what cancer cell treatment protocol is most likely to produce the most apoptosis 20 h after treatment?A.

The correct option is B: Administration of Compound 1 followed by Compound 2 after 0.5 h

Explanation:

Administering both compounds simultaneously (as suggested in option A) would mean that some cells might be exposed to and interact with compound 2 before being exposed to compound 1. It was observed by the researchers that if the chemotherapeutic agent (compound 2) is given a half hour after giving sensitization agent (compound 1) gives better results.

Active transport.

Explanation:

Active transport is defined as the movement of molecules or ions against a concentration gradient from a region of lower concentration to a region of higher concentration.

In plants, active transport is known as a mode of transportation. In plants against the concentration gradient, it uses stored energy to move the particles. Active transport in plant cells occurs in the root cells by absorbing ions or minerals (such as magnesium) and water.
