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.
Which way do molecules move during active transport?
hii friends?? hws life?? i think acitve transport moves molecules throught the speed of light and it needs blood and carbon dioxide to go through this process!!! Good luck people who need this answer bye!!! by: gabriel
During active transport substances move from regions of what?
in active transport, where do molecules always go
Why respiration rates may increase in root hair cell during the uptake of minerals ions?
Respiration rates may increase in root hair cells during the uptake of mineral ions because the minerals are taken up into the plant against the concentration gradient. This requires energy to use active transport, which then increases the rate of respiration.
What happens to a higher concentration of dissolved molecules on one side of a cell membrane during the process of diffusion?
the side of the cell membrane with the higher molecule concentration moves molecules to areas of lower concentration during diffusion until an equilibrium is reached between both sides of the membrane.
During diffusion molecules tend to move?
AnswerParticles move from regions of higher concentration to regions of lower concentration because of the concentration gradient,they move down gradient i.e from high to low concentration
Why does active transport require more energy than osmosis or faciliated diffusion?
It is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.

Are responsible for the transport of substances down a concentration gradient during facilitated diffusion.?
Carrier proteins

What are morphongens?
Any substance that governs the movement and development of cells during morphogenesis by forming a concentration gradient in the developing tissue
What are responsible for the transport of substances down a concentration gradient during facilitated diffusion?
Carrier proteins.
Why does active transport require more energy than osmosis or facilitated diffusion?
Active transport requires more energy than diffusion this is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
During active transport substances move from regions of what?
in active transport, where do molecules always go
What is only used in active transport?
A secondary active transporter. An example is Na+/glucose transporter. It has to move the glucose in but uses the sodium gradient to push it in instead of directly using ATP.Na gradient was made with Na/K ATPase which uses ATP (therefore it is called primary active transporter). In secondary active transport one molecule must have a higher gradient and uses ATP indirectly.
Will the dissolved oxygen in the water be absorbed during digestion?
Dissolved Oxygen can diffused through the membrane in digestion system by concentration gradient however the amount absorbed should be minimal or negligible.
Why respiration rates may increase in root hair cell during the uptake of minerals ions?
Respiration rates may increase in root hair cells during the uptake of mineral ions because the minerals are taken up into the plant against the concentration gradient. This requires energy to use active transport, which then increases the rate of respiration.
