Answer:
channels and chain-like structures
Explanation:
The plasma membrane contains channels that favor the transport of materials from both sides, i.e., from the intracellular medium to the extracellular environment. Membrane channels are a class of proteins that enable the passive transport of ions and chemical compounds by using the electrochemical gradient in both sides of the membrane. For example, channel proteins in the cell membrane known as aquaporins enable the transport of water across the cell membrane much more rapidly than by diffusion across this barrier.
Answer:
Partial hydrogenation
Explanation:
Vegetable oils naturally contain cis fatty acids. These fatty acids have double bonds and the two H atoms are on the same side of bond, producing a kink in the structure.
Cis fatty acids are converted into trans fatty acids by the process of partial hydrogenation or vegetable shortening. Hydrogen is added to convert some of the double bonds into single bonds but all double bonds are not removed. However, the cis double bonds end up getting converted to trans double bonds. H atoms are now on the opposite sides of the double bond. This arrangement makes the kink disappear from the structure hence trans fat is structurally similar to saturated animal fat. It increases the longevity of fats and makes it solid at room temperature but also has many side effects like increasing bad LDL cholesterol in blood.
