Question 36 1 pts Excluding water, what type of molecules makeup cells and living organisms Inorganic molecules Organic molecules Salts and ions All of the answers are correct

Answer 1

All of the answers are correct,

Organic Molecules, 1/3rd of body consists of organic molecules. Contain lots of carbon

major kinds of organic molecules: 1. carbohydrates 2. lipids 3. proteins 4. nucleic acids (include ATP) 5. vitamins

most larger organic molecules are polymers of smaller units:

carbohydrates $\rightarrow$ monosaccharides (simple sugars)

proteins$\rightarrow$ amino acids

fats $\rightarrow$ fatty acids & glycerol

nucleic acids$\rightarrow$nucleotides

Inorganic Molecules, 2/3rd ‘s of body consists of inorganic molecules

The major inorganic compounds are water (H2O), bimolecular oxygen (O2), carbon dioxide (CO2), and some acids , bases, and salts.

Salt and ions:

Electrolytes (ions) molecules that tend to disperse in solution into charged atoms

ions; eg Ca++ , Na+ , Cl - , K+ , et salts; NaCl, carbonates, phosphates acids and bases; HCl, NaOH

general functions of electrolytes:

a. help maintain salt/water balance

b. acid/ base balance

c. bone and teeth formation

d. functioning of nerve and muscle cells

e. enzyme activation
