<span>R group (or side chain) is an organic component of amino acids that is unique to each amino acid. </span> <span>Three of the amino acids have basic side chains at neutral pH: arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base and their pKa's are high enough that they tend to bind protons, (positive charge). Aspartic acid or aspartate (Asp) and glutamic acid or glutamate (Glu) are acidic amino acids because their side chains have carboxylic acid groups whose pKa's are low enough to lose protons, (negatively charged). The non-polar amino acids contain uncharged functional groups<span> at physiological pH and are incapable of participating in hydrogen bonding. </span></span>

Explanation:
carbohydrates are made up of carbon, hydrogen, and oxygen
hope this helps :) have a nice day !!
**please let me know if this was wrong**
Answer:
Lactic Acid Fermentation, which <em>produces the ATP molecule that animals and bacteria need for energy.</em> Lactic acid fermentation occurs when the ATP molecule is created without oxygen.
Alcohol/Ethanol Fermentation, which <em>causes certain sugars to be converted into alcohol and carbon dioxide</em> by bacteria on carbohydrate products/materials.
ATP stores and transports energy in the cells, usually in the mitochondria. Energy is released by hydrolysis (carbohydrates being broken down into sugar molecules), which eventually results in forming ADP (adenosine diphosphate) that absorbs the energy and recharges the phosphate group and ATP
