Answer:
B
Explanation:
Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient.
POLYMERIZATION of glucose produces glycogen, the storage form of sugar found in the liver and muscles.
When there is excess glucose in the blood stream, the body system usually convert such glucose to glycogen for storage in the liver and in the muscles. For storage, the glucose molecules are made to undergo polymerization reaction, during which glucose monomers are joined together to form polymer chains of glycogen.<span />
Answer:
With few exceptions, all cells in a person’s body have the same DNA and genes. As cells divide and grow different genes are expressed, resulting in different cell types. As cells divide and grow different genes are expressed, resulting in different cell types.
Explanation:
When a butter is treated with fatty acid desaturase,
the hydrogen atom will be removed and form a carbon double bond, which allow the
membrane to become more fluid. When temperatures change, a phase transition
occurs. If the temperature decrease, the membrane gels becomes solid which then
results to cracks and the imbedded proteins cannot partake in conformational
changes, thus it is important to maintain membrane fluidity.

Answer:
Carrier proteins are responsible for the facilitated diffusion of sugars, amino acids, and nucleosides across the plasma membranes of most cells.
