What else can I help you with?
Do substances in diffussion move with the concentration gradient?
Yes, substances in diffusion move from an area of high concentration to an area of low concentration, following the concentration gradient. This process continues until equilibrium is reached, with equal concentration on both sides.
Why do each villus have their own blood supply?
Each villus has its own blood supply to maximize absorption of nutrients from the small intestine. This allows for efficient exchange of substances between the villi and blood vessels, optimizing nutrient uptake from digested food. Having individual blood supplies also helps maintain a concentration gradient for effective absorption.
What are three physiological processes involved in absorption?
Three physiological processes involved in absorption are diffusion, active transport, and facilitated diffusion. Diffusion is the movement of substances from an area of high concentration to an area of low concentration. Active transport requires energy to move substances against their concentration gradient. Facilitated diffusion involves the use of carrier proteins to help substances move across a cell membrane.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What is the energy source for co-transport?
The energy source for co-transport is typically the concentration gradient of one substance that is established by an active transport process. This concentration gradient drives the movement of another substance against its own concentration gradient through a symporter protein.
Does passive transport move substances with the concentration gradient?
Yes, passive transport moves substances with the concentration gradient.
Is the movement of substances against their concentration gradient an active or passive process?
The movement of substances against their concentration gradient is an active process.
Does active transport move substances against the concentration gradient?
Yes, active transport moves substances against the concentration gradient.
Does active transport move substances against their concentration gradient?
Yes, active transport moves substances against their concentration gradient.
Does passive transport move substances against the concentration gradient?
No, passive transport does not move substances against the concentration gradient. It moves substances from an area of high concentration to an area of low concentration without requiring energy input.
Do substances in diffussion move with the concentration gradient?
Yes, substances in diffusion move from an area of high concentration to an area of low concentration, following the concentration gradient. This process continues until equilibrium is reached, with equal concentration on both sides.

What is the difference in the concentration of a substance across a space is called concentration?
The difference in concentration of a substance across a space is called a concentration gradient. It represents the change in concentration over a given distance and drives processes like diffusion and osmosis. Substances move from areas of high concentration to areas of low concentration along the concentration gradient to achieve equilibrium.
What moves against the concentration gradient in biological systems?
In biological systems, active transport moves substances against the concentration gradient.
What does concentration gradient have to do with diffusion of substances across the cell membrane?
The concentration gradient refers to the difference in concentration of a substance between two regions. In the context of cell membranes, substances tend to move from areas of higher concentration to areas of lower concentration to reach equilibrium. This movement is known as diffusion and it is driven by the concentration gradient.
What is The energy-requiring movement of materials against a concentration gradient?
Active absorption
