Answer:glucose
Explanation:Glucose is a simple sugar with the molecular formula C6H12O6. Glucose is the most abundant monosaccharide, a subcategory of carbohydrates. Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight
Primary active transport involves the movement of a solute against its electrochemical gradient facilitated by coupling to a process that provides the required free energy, e.g., Na+−K+ pump driven by ATP hydrolysis, whereas passive transport is always driven by the solute electrochemical gradient.
