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>

This is incorrect. Size and mass are not related. An example, a balloon that is filled with air can be compared to a bunch of iron that is of the same size yet it has much a smaller mass than the lump of iron.

Answer:
Translocation
Explanation:
Translocation is a chromosomal abnormality (mutation) in which a chromosome breaks and a portion of it reattaches to a different chromosomal location. It can occur during the formation of sperms and eggs during meiosis.
Translocation is of two main types: 1. Reciprocal location, in which two fragments break off from two different (non-homologous) chromosomes and switch places.
2. Robertsonian translocation, in which an entire chromosome (usually acrocentric) becomes attached to another chromosome (acrocentric) at the centromere to form a metacentric chromosome.
Translocation can either be BALANCED, where no genetic information is missing or additional. Hence, there is an even exchange with no adverse effect on the affected individual or UNBALANCED, where the exchange of chromosomal material is unequal resulting in an extra or missing genes.
