Answer:
<u><em>Proteins</em></u><em>:</em> used in facilitate transport across membrane
<u><em>Carbohydrates</em></u>: used to drive cellular respiration
<u><em>Lipid</em></u>: composes the cell membrane
<u><em>Nucleic acid</em></u>: used to create identical daughter cells in mitosis
Explanation:
A. In the cell membrane, transport proteins or channels are present which selectively allow the transfer of molecules. This is why the cell membrane is also known as a selectively permeable membrane.
B. In cellular respiration, which takes place in mitochondria, glucose (carbohydrate) is used to generate ATP molecules.
C. The cell membrane is composed of a lipid bilayer that contains protein channels. This makes the membrane insoluble in water and maintains the integrity of the cell.
D. The nucleic acid is the hereditary material that can replicate and transfer genetic information to the next generation.
Believe it or not, ice is actually about 9% less dense than water. Since the water is heavier, it displaces the lighter ice, causing the ice to float to the top. How is ice less dense than water? ... So for water, the density actually decreases along with a decrease in temperature - causing ice to be less dense than water!
D)Electron transport chain
The cell stays in the interphase stage the longest. The interphase stage includes the G1 phase which is the initial growth of the cell. Next is the S phase and in simple terms it’s just the replication of the DNA. Next is the G2 phase which is the continued phase of cell growth. After interphase is completed, the cell enters prophase, then metaphase, then anaphase, then telophase, and finally cytokinesis.
Answer:
The specific reaction of an enzyme depends on its active sites, which has shapes that closely matches the shape of its substrates. Upon substrate binding, the enzyme changes shape slightly in a way that allows the chemical reaction to happen more readily, thus reducing the activation energy of the reaction.
