Answer - Well to put it in short terms.
Cells such as water cells or aquatic microorganisms need and required to have a large surface area increased. Because this helps them stay afloat without spending much amount of energy to float.
The Energy-Requiring Steps of Glycolysis. In the first half of glycolysis, energy in the form of two ATP molecules is required to transform glucose into two three-carbon molecules.
All types of Active transport require ATP:
-Active transport
-Endocytosis
-Exocytosis
