What is a macrocolecule?
A biological macromolecule is a very large molecule that is built from smaller biological, or organic, molecules that are linked together by covalent bonds.
Macromolecules are necessary for an organism’s growth and survival
There are four major classes of biological macromolecules. Carbohydrates, Proteins, Fats, and Nucleic acids (DNA and RNA)
What do you notice about the atoms that make up these molecules?
Carbs-They contain carbon, hydrogen, and oxygen and include the sugars, starches, and fibers that are found in grains, fruits, and vegetables.
Carbohydrates are important for brain function, and they provide energy for working muscles and the central nervous system.
Protein- This type of macromolecule can be found in meats, poultry, fish, eggs, dairy products, nuts, and legumes.
Protein is necessary for building and repairing muscle mass, and it helps maintain a healthy immune system.
There are about 20 amino acids,most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulfur.
Fats-are used by the body as energy and to store fat-soluble vitamins (vitamins A, D, E and K). They also insulate the body and protect vital organs.
The human body stores excess fat in specialized cells called adipocytes.
consists of two main components—glycerol and fatty acids.
What happens to macromolecules from food during digestion?
Glycolysis can be best explained as a series of chemical reactions that extract energy from glucose. This process occurs in liver cells. At the start of glycolysis, a molecule of glucose (C6H12O6) is trapped and destabilized, or broken down into two three-carbon molecules. These molecules are called pyruvate. The net products of the process are two molecules of ATP—four molecules of ATP are actually produced, but two are used up—and two molecules of NADH. The liver also metabolizes other macromolecules,
If there is not enough carbohydrate intake, how does the body form glucose?
When there is a shortage of fats or carbohydrates, proteins can also yield energy.
Fats typically provide more than half of the body's energy needs.
If not enough protein is provided by the diet, the body starts chewing on muscle cells.
If there is a glucose shortage, how does the body produce energy?
glucose can be made in the liver and kidneys using protein from elsewhere in the body.
What atoms make up sugar molecules, amino acids, and fatty acids?
Sugar molecules - Glucose, Amino Acids - Proteins, Fatty Acids - Fat
Explanation:
These are the questions that you're supposed to answer in the essay. just arrange them into an essay format and change some stuff and add more so its not plagiarized. or just write the thing on your own bc thats what youre supposed to do : )
