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>

Hello
Most eukaryotic cells that are not involved in the production of gametes undergo mitosis. These cells, known as somatic cells, are important to the survival of eukaryotic organisms, and it is essential that somatic parent and daughter cells do not vary from one another.
Hope this helps
Plz mark me as brainliest
She noticed a pressing human need, this is why she formed the American Red Cross.
<span>are elaborate folds on the inner membrane which hold the enzymes and electron carriers of aerobic respiration.</span>
I would say B) because the rest dosnt quite make sense to me and A) the gravity of the sun would still be the same despite the shape if we have an triangle block and an sphere then drop the they are going to drop at the same speed the gravity is not going to sphere is not going to fall faster
