Homework Answers
Ans Secondary active transport. Symport of hydrogen and glucose, against gradient of glucose and energy is indirectly used.
Primary active transport- solute accumulation is directly linked to energy use.
In facilitated diffusion, with the help of transporter membrane proteins, is used for transport of polar compounds and ions
In Simple diffusion, is dependent on concentration gradient, not against gradient.

33) Which of the following is most likely true of a protein that cotransports glucose and sodium ions into the intestinal cells of an animal? A) Sodium and glucose bind to the same site on the cotransporter. B) Transport of glucose against its concentration gradient provides energy for uptake of sodium ions against the electrochemical gradient. C) Sodium ions can be transported whether or not glucose is present outside the cell, but glucose transport requires cotransport of sodium ions. D)...

Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Channels The integral proteins involved in facilitated transport are collectively referred to as transport proteins, and they...
