Answer:
Carbs - provide your body with energy.
Lipids - serve as structural components of cell membrane, function as energy storehouses, and function as important signaling molecules.
Protein - helps with growth and maintenance of tissues, enzymes that cause biochemical reactions in and out of your cells, some proteins are hormones so it acts as a messenger the aid communication between your cells, tissues, and organs. And many other thing that are a google search away.
Nucleic Acids - hold storage and expression of genetic information
Answer:4,500
Explanation:6mm times 750 equals 4,500
As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
Biochemistry is the study of the actions of the main metabolic processes of living organisms, which are protein synthesis (DNA and RNA molecules, genetic codes and how they work, enzyme formation and function, etc), glycolysis (cellular respiration, aka the Krebs cycle/citric acid cycle to break down glucose molecules to release chemical energy and oxydative phosphorylation, the use of that chemical energy to form ATP molecules in which the chemical energy is put in a form the cell can use, and lipid chemistry (the study of the pathways in which fatty acids are formed into lipids and fat molecules and cholestrol formation and function).
Essentially, biochemistry covers the chemical reactions necessary for cellular and organism metabolism
I would say (C) considering all of the others seem positive
Hope this was helpful!! :)
