Answer: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides.
Explanation: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides. They are then transported across the alabaster membrane via facilitated diffusion. Di and tripeptides are absorbed via separate H+ dependent cotransporters and once inside the cell are hydrolyzed to amino acids.
Answer:
They are major components of the cytoskeleton
Explanation:
They are found in all eukaryotic cells and are involved in mitosis , cell motility, intracellular transport and maintanance of cell shape
Answer is: coupled transport differs from primary active transport due to the fact that it uses electrochemical potential difference as a direct source of energy.
Primary active transport directly uses metabolic energy (adenosine triphosphate- ATP) to transport molecules across a membrane.
In secondary active transport (coupled transport) there is no direct coupling of ATP, <span>energy derived from the pumping of protons across a cell membrane.</span>
