Which of what? What’s the rest
I am pretty sure it’s Ribosine
When grapes are soaked in water, the grapes then swell up because grape's cells have a high concentration of solutes in comparison to the water. In other words, grapes have low concentration of solvent (that is water molecules ) in comparison to the concentration of solvent in water. In this situation, there will happen a process known as osmosis in which water molecules moves from a region of concentration of water to a region of low concentration of water through a semipermeable membrane. (the cell membrane of the grape's cell is also semipermeable,which only allows solvent molecules to pass through it)
Active transport is a type of transport that requires energy to move substances across a membrane. It occurs against a concentration gradient.
- The use of energy to move waste materials out of a cell is an EXAMPLE of transport active.
- Active transport occurs against a concentration gradient, whereas passive transport (i.e., diffusion) occurs in favor of a concentration gradient.
- Active transport can be mediated by membrane proteins that move substances from an area of high concentration to an area of low concentration.
- This movement (active transport ) usually requires the energy provided by the hydrolysis of ATP.
- Water molecules move across cellular membranes through membrane protein channels called aquaporins that act in favor of a concentration gradient (passive transport).
