In my opinion, the best answer among the choices listed above is option D. The reason why scientists use models because they can <span>represent things that are too small to see. Models are used to describe and explain certain phenomena. Hope this answers the question.</span>
Answer:
D: Simple Diffusion
Explanation:
Diffusion is a transport driven by a concentration gradient. Gas molecules move from a place of high concentration to an area of low concentration. Knowing when blood is low in concentration and high in carbon dioxide it goes under gas exchange with air into the lungs.
Hope this helped! :)
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.
