Post 4 - Senses and Stuff
Taste is produced by the process of the proteins on your tongue that bind to anything that goes into your mouth which sends a signal to the brain to produce that sense. There are two genes that make up your taste of sweetness, and it's important because sweetness is an indicator that a substance is rich in carbohydrates. Most mammals have these genes, but all cats lack the base pair of amino acids that make up the gene. This is why cats are unable to taste sweetness. I thought it was cool that the genes that make up the proteins on your tongue allow you to distinguish the taste between different substances that go into your mouth.
