Molecules are moving against a 'concentration' gradient. Active transportation moving from low to high concentration, while passive transportation such as osmosis and diffusion go from high to low concentration.
No energy is needed because it's a part of passive transport, not active transport.

Active transport requires energy in the form of ATP (adenosine triphosphate) to move substances against their concentration gradient across a cell membrane. This process is essential for maintaining proper cellular function and balance.
The energy needed for active transport is usually supplied by ATP, adenosine triphosphate. ATP provides the necessary energy for transporting molecules across a cell membrane against their concentration gradient. This process is essential for maintaining cell homeostasis and various cellular processes.
Passive transport does not require energy input and relies on the concentration gradient to move molecules across the cell membrane. Active transport requires energy (usually in the form of ATP) to move molecules against the concentration gradient.
No energy is needed. Transportation costs no ATP
Active transport involves the movement of molecules against their concentration gradient, requiring energy input. Two methods of active transport include primary active transport, where energy from ATP is directly used to move molecules, and secondary active transport, where the movement of one molecule down its gradient provides energy to transport another molecule against its gradient.
facilitated
Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell. ACTIVE TRANSPORT REQUIRES ENERGY. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. PASSIVE TRANSPORT REQUIRES NO ENERGY.
of course it is break glucose into pyruvic acid.
Energy comes from fatty acids which form from excess glucose( sugar) and lipids( fats). When energy is needed these fatty acids cross into the mitochondria and are broken down into acetyl choline- which is the energy block. Animals, therefore, transport energy in fat cells.
Processes that require ATP cellular energy include muscle contraction, active transport of molecules across cell membranes, and cellular respiration to generate energy in the form of ATP. Additionally, ATP is needed for biosynthesis of molecules, DNA replication, and cell division.
