Cellular Respiration
In the molecule CO2, explain why carbon can form a double bond with oxygen.
Carbon has 4 electrons in its outer shell and needs 8 to be stable. Oxygen has 6, and needs 2 to be stable. By sharing 2 pairs of electrons with each oxygen, each atom fulfills the requirement for a stable arrangement.
Why don't polysaccharides taste sweet?
By the time they're fully broken down they are no longer near your taste buds
Why do double bonds in unsaturated fats make them liquid at room temperature?
the molecules take up more space due to the double bond
What is the monomer of a nucleic acid
nucleotide
