Atoms in triglycerides could be used in the synthesis of DNA. Acetyl-CoA is the metabolic intermediate involved in Citric acid cycle pathway which functions as crossover points between triglycerides and DNA.
The Citric acid cycle also known as Krebs cycle or TCA cycle (tricarboxylic acid cycle) involves a series of enzyme-catalyzed reactions which occur in the mitochondrial matrix. In this pathway, acetyl-CoA is oxidized to form carbon dioxide and the coenzymes are reduced, which generate ATP in the electron transport chain.
Acetyl-CoA (acetyl coenzyme A) takes part in many biochemical reactions linked with protein, carbohydrate and lipid metabolism. Its main role is to deliver the acetyl group to the Citric acid cycle (Krebs cycle) to be oxidized for energy production.

Absence of oxygen means anaerobic respiration ; which has 2 different pathways.
First Pathway ; Alcoholic fermentation which takes place in yeast.
Pyruvate is decarboxylated into ethanal releasing co2 as waste product.
Ethanal is toxic , so its reduced by help of NADH to ethanol in presence of alcohol dehydrogenase enzyme , and Free NAD is released to continue glycolysis.
2) The second pathway is Lactic fermentation which takes place in mammalian muscles.
Pyruvate accepts hydrogen and is converted to lactate by the help of enzyme lactate dehydrogenase , again free NAD is released to continue glycolysis.
Hope I made it clear enough :)
Answer:
Taking into account the principle of osmosis, the question that best addresses experimental design is <em>How does the effect of environmental sucrose concentrations impact the movement of water across a membrane?</em>
Explanation:
The experimental design of the student, made with dialysis bags and sucrose at different concentrations should recreate the principle of osmosis, of importance in living beings for organic homeostasis.
Osmosis consists of the movement of water - through a semi-permeable membrane - from a less concentrated solution to a higher concentration solution, following a gradient, to achieve balance.
The student will observe in his experiment that water moves from the solution with less sucrose concentration to the higher concentration of sugar. Beakers with the highest concentration of sucrose will have the highest weight, due to the increase in liquid volume.
How does the effect of environmental sucrose concentrations impact the movement of water across a membrane?
The experiment shows that:
- The water from the beaker with less sucrose concentration moved -through the dialysis tubes and the membrane- to the beaker containing the most concentrated sucrose.
- Different sucrose concentrations will attract different amounts of water, which influences the final weight of each container.
With this experiment the principle of osmosis is confirmed, where the concentration of a solute determines the amount of water that passes through a semipermeable membrane -following a concentration gradient- until equilibrium is reached.
