Explanation:
i found it out the hard way
Natural selection could not occur without environment, and a act on animal.
Enzymes are (usually) specific to the substrates they bind to. Thus, each enzyme has one and only one substrate structure they can metabolize, so even substrates with similar structures cannot be broken down by an enzyme specific to one of them.
(hi, i dont know about this one personally, but i found an answer somewhere else on the internet thatll hopefully help u)
Answer: They consist of long chains of C, H, and O.
Explanation:
In terms of chemical composition, lipids differ from nucleic acids and proteins because they mostly just contain carbon, hydrogen, and oxygen (except for phospholipids which of course contain phosphorous). In addition to those elements, proteins contain nitrogen and sulfur, and nucleic acids contain nitrogen and phosphorous.
Carbohydrates share the C, H, and O composition as lipids, but they differ in structure. Lipids are generally exist as triglycerides, which consist of a triple hydroxyl alcohol (glycerol) that has bonded to three long-chain carboxylic acids (fatty acids) in a triple condensation reaction. Carbohydrates on the other hand are made of carbon ring structures that either remain alone or polymerize into long polysaccharide chains.
