Verified step by step guidance1
Understand the concept of active transport: Active transport is a cellular process that moves molecules across a cell membrane against their concentration gradient, which requires energy.
Identify the molecule that provides energy for cellular processes: ATP (adenosine triphosphate) is the primary energy carrier in cells, providing the energy needed for various cellular activities, including active transport.
Recognize the role of ATP in active transport: ATP provides energy by hydrolyzing into ADP (adenosine diphosphate) and an inorganic phosphate, releasing energy that is used to power transport proteins in the cell membrane.
Differentiate ATP from other molecules listed: NADH is involved in electron transport and cellular respiration, oxygen is a reactant in cellular respiration, and glucose is a source of energy but not directly used in active transport.
Conclude that ATP is the molecule that provides the energy required for active transport processes in cells, as it directly supplies the energy needed for the movement of molecules against their concentration gradient.
