The major role of these proteins is transport role: they act as a channels that undergo conformational change in order to move a substance through the membrane.

Answer:where are the flowers????????????????
Explanation:
The tropical rainforest is the moist biome which is present near the equator of the Earth. These rainforests receive an average of 60-160 inches of rainfall per year with no dry season throughout the year. In these forests, the canopy of the trees prevent the sunlight from reaching the floor of the forest. This makes it difficult for the vegetation to survive on the floor as sunlight is essential for the growth of the vegetation on the floor.
Hence, the correct answer is 'option - C - sunlight'.
