In the diagram, which one represents carrier-mediated facilitated diffusion?

Molecules such as glucose are transported across plasma membranes by special protein carriers. Carrier-mediated transport in which the net movement is down a concentration gradient, and which is therefore passive, is called facilitated diffusion. Carrier-mediated transport that occurs against a concentration gradient, and which therefore requires metabolic energy, is called active transport. A membrane carrier is used for the transported substance. The carriers (as in the active transport) are proteins embedded in the cell membrane. The facilitated diffusion is faster than simple diffusion, but as the concentration of the transported substance increases, the carrier is saturated and the rate of facilitated diffusion stops increasing.

Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane. A concentration gradient is a just a region of space over which the concentration of a substance changes, and substances will ... Facilitated diffusion... In this type of transport process, a solute (e.g. glucose) binds to a specific carrier protein on one side of the membrane. This binding induces a conformational change in the carrier protein that results in the solute moving down its concentration gradient to the other side of the membrane primary active transport Uniporter is a carrier that transports only one substrate in a complete cycle; the process is known as facilitated diffusion or uniport, and is always passive. Shown in the figure is a glucose uniporter at the basolateral membrane. Symporter is a carrier that transports at least two substrates in the same direction in each cycle.

Ans: This figure represents protein synthesis. Step one, the initiator tRNA attaches to a start codon. In step two, the large and small ribosomal subunits join to form a functional ribosome and initiator tRNA fits into P site. In step three, the anticodon of an incoming tRNA pairs with the next mRNA codon at A site. Step four, the amino acid on the tRNA at P site forms a peptide bond with the ...

Facilitated diffusion is the passive movement of molecules along the concentration gradient. It is a selective process, i.e., the membrane allows only selective molecules and ions to pass through it. It, however, prevents other molecules from passing through the membrane. The electric charge and pH helps in the diffusion across the membrane.
