light reaction
Photosynthesis is the reaction that requires direct energy from sunlight to produce energy carrier molecules like ATP and NADPH in plants.
The process described is photosynthesis, which occurs in plants and some bacteria. Photosynthesis uses sunlight to convert carbon dioxide and water into glucose (energy carrier) and oxygen. The energy from sunlight is captured by chlorophyll in plant cells and used to drive this chemical reaction.
Air is a better carrier of sound than vacuum. In air, sound waves can travel because air molecules can vibrate and transfer energy. In a vacuum, there are no molecules to transmit sound waves, so sound cannot travel.
NADH and ATP
Active transport in the small intestine requires a carrier protein and energy (in the form of ATP) to move nutrients against their concentration gradient into absorptive cells. This process allows the absorption of nutrients like glucose and amino acids that are present at lower concentrations in the intestines compared to inside the absorptive cells.

Yes, the movement of molecules against a concentration gradient requires the use of a carrier protein or active transport mechanism in order to transport the molecules from an area of lower concentration to an area of higher concentration. This process requires energy to move molecules against their natural gradient.
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
A cofactor or coenzyme can attach to a protein to help catalyze a metabolic reaction by facilitating the reaction or acting as a carrier of chemical groups. These molecules can be inorganic ions, organic molecules, or other proteins that work together with the protein to enable the reaction to occur.
Facilitated diffusion is a type of passive transport that requires special carrier proteins to help molecules move across the cell membrane. These carrier proteins assist in the movement of specific molecules that cannot cross the membrane on their own.
Facilitated diffusion requires the presence of specific carrier proteins embedded in the cell membrane to help transport molecules across the membrane. These carrier proteins assist in the movement of molecules down their concentration gradient without requiring energy input from the cell.
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
Carrier molecules are not involved.Different between chemical potential leads the diffusion
Active absorption requires energy in the form of ATP, carrier proteins or channels in the cell membrane for transporting molecules against their concentration gradient, and an appropriate gradient across the membrane to facilitate movement. Additionally, active absorption may involve specific binding sites on carrier proteins for the molecules being absorbed.
No, filtration does not require a membrane-bound carrier for transport. Filtration is a passive process that relies on pressure gradients to separate particles based on size. It does not involve specific carriers to transport molecules.
