Lyrx [107]

Answer: Pyruvate is reduced and NADH is oxidized.

Explanation:

Fermentation is a chemical process that involves the breakdown of carbohydrates anaerobically by the activities of microorganisms.

It is the process use in the production of foodstuffs, wine and beer. Fermentation start with enzymes activities, which breakdown sugars into lactate or two molecules of three carbon organic acid, pyruvic acid. Pyruvate is reduced to lactic acid or alcohol in the absence of oxygen and nicotinamide adenine dinuleotide+hydrogen(NADH) is oxidized . This process produces two ATP per glucose molecule.

What is embedded in the phospholipid bilayer that helps in the movement of larger molecules ?

gladu [14]

Answer:

$\boxed {\boxed {\sf A. \ Channel/Transport \ proteins}}$

Explanation:

The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.

Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.

So, salt, water, and fats do not contribute to the movement of larger molecules, but <u>channel or transport proteins do and choice A is correct. </u>
