Carrier proteins are involved in passive transport, moving solute molecules form one side of the membrane to the other. Option (A) is not true. <em>They increase the </em><em>speed of transport</em><em> across the membrane. </em>
<h3>Facilitated diffusion </h3><h3 />
- It is the transport of hydrophilic molecules that can not freely cross the membrane.
- Channel protein and many carrier proteins are in charge of this transport.
- When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one.
- When ions need to cross the membrane, the process depends on an electrochemical gradient
<h3>Carrier molecules</h3><h3> </h3>
- Carrier proteins move molecules from one side of the membrane to the other side.
- They do not need energy. They move solutes according to the electrochemical gradient.
- The carrier proteins have specific binding sites recognized by the transported molecules.
- When the proteins and the solutes get together, the carrier proteins suffer a temporal change in their structure.
- These changes allow the solute passage to the other side of the membrane.

Options,
(A) They increase the speed of transport across the membrane. FALSE
(B) They concentrate solute molecules on one side of the membrane TRUE
(C) They have specific binding sites for the molecules they transport. TRUE
(D) They undergo conformational changes upon binding the solutes. TRUE
The incorrect option about carrier proteins is A. <em>Carrier proteins </em><em>Do Not increase</em><em> the </em><em>speed</em><em> of </em><em>transport</em><em>. They just make it possible. </em>

The genotypes for the parents should be RR and rr. I hope this helps!
I believe that the answer is that proteins help in the growth and development of the body.
Hope this helps! :)
The neurons are connected, with a tiny gap between them called the
synapse, by dendrites. Neurotransmitters are chemical compounds that
carry signals across the synapse.
I will revise the simulation so users can evaluate the role of human activity in the pH of the ocean by lowering the temperature.
<h3>What is pH?</h3>
This is referred to as power of hydrogen and is the measure of acidity or alkalinity of a substance.
The variables which would be changed in the simulation to accomplish it is the increase in oxygen levels.
