Describe factors that influence protein shape.

proteins are only able to function properly in their specific shape, they will typically stay in that configuration unless something forces them to change. When proteins change their shape, this is called denaturation. Some external forces that affect protein shape are pH and temperature

cats appear to have glowing cat eyes because the back of their eyeballs includes a special reflective surface called the tapetum lucidum. this lets them see better during the night, giving them a much better vision.
