Explain why polar and charged molecules tend to be soluble in water
Water is polar
How is covalent bond different from ionic bond
Ionic bond is two oppositely charged ions, covalent bond is electrons sharing atoms.
Compare and contrast potential and kinetic energy
Kinetic energy is in motion and potential energy is stored.
Difference between saturated and unsaturated fat’s
Saturated fats have two hydrogen Atoms for every one carbon. Unsaturated fats have less than two for every one or more hydrogen atoms.
Describe the process of dehydration synthesis
Smaller molecules called subunits are joined by covalent bonds
Why does proteins have unlimited varies of shapes
Shave can change and presence of charged or polar molecules
What’s the importance of enzymes in living organisms?
