Question

Question 9 Lipids and proteins can be formed from carbohydrates. Which elements do these molecules have in common that help form different molecules? carbon hydrogen sodium oxygen

Answer 1

the main answer is carbon although its really carbon, hydrogen, and oxygen

to remember each macromolecule, you can use this reference...

Carbohydrates = CHO (carbon, hydrogen, oxygen)

Lipids = CHO (carbon, hydrogen, oxygen)

Proteins = CHON (carbon, hydrogen, oxygen, nitrogen)

Nucleic Acids = CHONP (carbon, hydrogen, oxygen, nitrogen, phosphorus)

hope this helped :)

Answer 2

carbon if only one answer allowed, if check multiple, carbon, hydrogen, and oxygen.

Step-by-step explanation:

The common elemental ingredients are carbon, hydrogen, and oxygen. They all contain the element carbon. They contain simpler units that are linked together making larger molecules.
