Because of similarities in the kinetics of enzymatic reactions and of active intestinal transport, the effect of actinomycin D on the latter was investigated. Observations were made of the active ...

IT is well established that the active transport of hexoses and amino-acids in the intestine is dependent on sodium. To account for this, Crane 1 suggested a coupling between sodium and hexose ...

or secondary active transport. The small intestine is good for absorption since it has a large inner surface area. This is formed due to the plicae circulares which project many tiny finger-like ...

This is taken from the gut wall, inside the small intestine, into the blood ... Animals therefore use active transport to absorb glucose into the blood under these conditions.

During the past few years there has been much interest in defining the biochemical basis for the effects of vitamin D and glucocorticoids on calcium transport across biologic membranes.

Active transport is a process that moves molecules ... The glucose molecules in the intestine might be in a higher concentration than in the intestinal cells and blood - for instance, after ...

Active transport involves molecules moving against ... such as fat droplets in the small intestine. Phagocytosis is a process for cells to absorb solid particles. In exocytosis, cells, expel ...
