What type of cellular transport moves molecules from low to high concentrations? A)proteins pumps
B)diffusion
C)osmosis
D)passive transport

A. Protein pumps

Explanation:

Molecules usually move down their concentration gradient - in other words, they move from high to low concentration.

Here, in the problem, we are moving molecules against their concentration gradient - from low to high. So, we require an input of energy.

Look at each of the answer choices:

A) Protein pumps

Protein pumps do require an input of ATP (energy), in order to push molecules up their concentration gradient. This is the answer.

B) Diffusion

Diffusion is the transport of molecules down their gradient, from high to low concentration, so this is wrong.

C) Osmosis

Osmosis is essentially diffusion of water molecules, so it's again from high to low concentration. This is wrong.

D) Passive transport

Like the name suggests, this transport is "passive", or it doesn't require energy. Because it doesn't require energy, we know it moves molecules down their concentration gradients. This is wrong.

The answer is thus A.

a adaptation is when organism changes itself to fit the environment

ex. when its cold outside i wear a jacket

hello everyone my name is nevaeh, i know everyone needs in some way, shape, or form and i am willing to provide. i set up a google classroom where people can ask me questions and get on work. no question is a stupid question so do not be afraid to ask. i usually only focus on core subjects but if you ask i will with other specialized subjects. i can do essays all the way to power points : )

my google classroom is the code is 7hr2k4
