NGSS.MS-PS2-2

biomolecule that provides quick energy and regulation of blood glucose. It will prevent the degradation of skeletal muscle and other tissues such as the heart, liver, and kidneys. It prevents the breakdown of proteins for energy.

• Carbohydrates

• lipids

• proteins

• nucleic acids

Functions of this macromolecule include storing energy, signaling, and acting as structural components of cell membranes.

• proteins

• nucleic acids

• Lipids

• carbohydrates

This macromolecule does most of the work in cells and is required for the structure, function, and regulation of the body's tissues and organs.

NGSS.HS-LS1-1

a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.

• Proteins

• Nucleic Acids

• Lipids

• Carbohydrates

List the steps (chemical/enzymatic) of carbohydrate digestion

• 1. in mouth, salivary glands secrete saliva which helps moisten food

  2. in mouth, salivary glands release enzyme amylase which begins breaking apart the macromolecule (polysaccharide - carbohydrate) into simple sugars (monosaccharide)

  3. there is no chemical digestion of carbs in stomach

  4. in small intestine, pancreatic enzymes further break down the carbs into monosaccharids which are then absorbed

  5. in large intestine, bacteria breaks down previously undigested carbohydrates and non-digestible carbs like cellulose (fiber) are excreted with feces

• 1. in mouth, salivary glands secrete saliva which helps moisten food

  2. in mouth, salivary glands release enzyme amylase which begins breaking apart the macromolecule (polysaccharide - carbohydrate) into simple sugars (monosaccharide)

  3. there is no chemical digestion of carbs in stomach or small intestine

  4. the undigested carbohydrates are broken down by intestinal bacteria and excreted with feces
