Vinblastine is a standard chemotherapeutic drug used to treat cancer. Because it interferes with the assembly of microtubules, its effectiveness must be related to Group of answer choices disruption of mitotic spindle formation. inhibition of regulatory protein phosphorylation. suppression of cyclin production. inhibition of DNA synthesis.

The correct answer is ''disruption of mitotic spindle formation.''

Explanation:

Vinblastine blocks mitosis by inhibiting the formation of microtubules in the mitotic spindle, which results in the interruption of cell division in the metaphase stage, thus having a specific action of the M phase of the cell division cycle . Its activity may also be related to an interference of the amino acid metabolic pathways that lead from glutamic acid to the citric acid cycle and to urea.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
