Which movement of substances through a cell membrane against a concentration gradient requires energy?

Biology

raketka [301]3 years ago

The answer to this is active transport. 

This is a kind of movement of substances. Unlike diffusion or osmosis, the substances move against the concentration gradient (ie. from low concentration to high concentration). This process requires extra energy generated such as from cellular respiration. 

In addition, this process also requires a carrier protein, where it'll pick up certain substances that are needed to transport and move it to the other side. Some examples of movements of active transports are such as root hair cells of plants picking up minerals, or our small intestine absorbing nutrients digested.

Why is it protective for the crayfish to have its nerve cord on the bottom of its body?
mr Goodwill [35]
The crayfish have its nerve cord on the ventral side rather than on the dorsal side. The ventral side is under the Crayfishes' exoskeleton, as opposed to the dorsal side where the exoskeleton is . If it is attacked it will be from the dorsal side and the nerve cord would be snapped easier. The function of the nerve cord is that if it gets attacked by a predator they will go for the top and it will still be able to move.
