Facilitated diffusion is a process by which molecules and ions are transported from one location to another with the aid of some intermediary, such as a protein. In biology, diffusion usually refers to the movement of molecules or ions across a membrane, though it can also occur through liquid...

To solve the question regarding the synthesis of ATP by enzymes present on thylakoids, we will analyze the process of ATP synthesis and identify which option is not involved.1. Understanding the Thylakoid Structure: - The th
Active transport is mediated by carrier proteins that have the same characteristics of specificity and saturability described for facilitated diffusion. A main example of active transport is the maintenance of ion gradients across cell membranes, which depends on the function of specific carriers or “...
1). The diffusion component would be expected to contribute more to uptake under conditions where blood FA are increased such as with active intravascular lipolysis of lipoprotein triglycerides. This component is likely to become more significant after exposure to lipolytic agonists that induce FA ...
Writing in Nature in 1939, Chaik and Duthie suggested, "… it seemed to us likely that it was an enzyme acting on some substrate in the skin, causing the removal of a barrier to the rapid diffusion of intradermally injected fluids."14 The enzyme activity was subsequently defined as a ...
(2) the continuous perilymphatic perfusion minimised unstirred layer effects, which therefore did not contribute significantly to the resistance of water diffusion across the plasma membranes of the cochlear duct epithelium; and (3) the pre-existing osmotic gradient between the endolymph (304.2 mOsm ...
