Since nutrients are absorbed through the surface of the cell membrane, and nutrients are needed by the entire volume of the cell, a smaller Surface Area / Volume ratio would mean the cell has a better ability to "feed" itself.
The cell needs to take in nutrients like carbohydrates and amino acids, and it also needs to release certain metabolic waste products. Such molecules are either pushed throughout the membranes by membrane transporters as well as diffuse passively along protein channels in assisted diffusion.
The ratio of surface area to volume declines with cell expansion. This is due to the fact that as a cell expands, its volume (internal contents) develops more quickly than just its surface area (its cell membrane).

What molecule in cells provides the immediate energy needed for biochemical reactions?.
Molecule in cells provides the immediate energy needed for biochemical reactions is ATP (Adenosine Triphosphate).
Understanding ATPATP is soluble in water because it has phosphatehydride bonds. The phosphatehydride bond of ATP is very unstable, easy to break but easy to reconnect.
This is why ATP can immediately release large amounts of energy when it is needed very quickly. This allows us to move the body quickly without any pause between the mind moving and the movement itself.
ATP formationATP is formed from the glycolysis process that takes place in the mitochondria. Mitochondria are cell organelles that have an internal membrane where glycolysis takes place.
Glycolysis is the reaction of breaking down glucose from food into pyruvic acid and ATP. The pyruvic acid is further broken down to produce ATP and tricarboxylic acid.
ATP is produced according to the amount of food that enters the body, and can be used up when used to move. When you exercise, the amount of ATP used by the body is more than when you only play with your cellphone.

Blood is called tissue give reason
Blood is both a tissue and a fluid. It is a tissue because it is a collection of similarly specialized cells that serve particular functions. These cells are suspended in a liquid matrix (plasma), which makes the blood a fluid.
Explanation:Blood is considered a type of connective tissue because it connects the body systems, transports oxygen and nutrients to all the parts of the body, and removes waste products. Blood has an extra-cellular matrix called plasma, with red blood cells, white blood cells, and platelets floating in it. Blood is a specialized form of fluid connective tissue. Blood is regarded as a connective tissue because as the blood is circulated throughout the body due to the pumping action of the heart, it carries different materials and gases from one part of the body to another. Hence, it connects different tissues and organs of the body and thus, is called connective tissue. It is considered a connective tissue because it consists of blood cells surrounded by a nonliving fluid matrix called blood plasma. It is the most atypical connective tissue: the fibres of blood are soluble protein molecules that become visible during blood clotting.

why is fructose toxic to liver cells, but not muscle cells, in individuals with a defect in the enzyme aldolase b?
Fructose is toxic to liver cells, but not muscle cells, in individuals with a defect in the enzyme aldolase, because muscle cells employ hexokinase to convert glucose to glucose-6P, which cannot be further metabolized, liver cells cannot.
In the second stage of the metabolism of fructose, aldolase B is in charge of converting the compound fructose-1-phosphate into glyceraldehyde and dihydroxyacetone phosphate. Aldolase B is also involved in the breakdown of the simple sugar glucose, but to a lesser extent. The lack of the enzyme aldolase B is a defining feature of the autosomal recessive condition known as inherited fructose intolerance.
Fructose-1-phosphate is broken down into glyceraldehyde and dihydroxyacetone phosphate by the crucial enzyme aldolase B. Phosphate depletion and fructose 1-phosphate buildup in the liver are symptoms of aldolase B deficiency. As a result, gluconeogenesis and glycogenolysis are suppressed, which inhibits the synthesis of proteins and causes liver failure.
