Answer:
Explanation:
A. False - A symporter system requires that one of the molecules to be transported using passive transport.
B. True - The Na+ will move down the established concentration gradient releasing energy to facilitate movement of sucrose against its concentration gradient. This is known as secondary active transport.
C. False - sucrose moves through ion channels not by diffusion to better control its movement across the membrane.
D. True - Movement of molecules against their concentration gradient thus requiring energy input is known as active transport.
E. False - One of the molecules needs to be moving against its concentration gradient.
F. False - A Uniporter system allows the binding and transport of a single molecule at a time. A symporter allows simultaneous binding and transport of Na+ and sucrose molecules.

Answer:
it is because this Complex carbohydrates always takes longer time to digest and are a more sutiable source of energy than simple carbohydrates. ... As also the complex carbohydrates have more longer chains, and they take more time longer to break down and provide more lasting energy in the body than simple carbohydrates. Both types of carbohydrate are often present in many foods.
