Singing from my diaphragm and my throat?

My throat keeps moving when I sing?

• Im just an amatuer singer and I've been doing research on how to sing. I know there's already billions of questions asking how to sing. But every time I try to properly sing (singing from diaphragm), my throat moves. For example, if I play a C and then down to a D, my throat moves. But in no way am I putting any tension on throat(or least I hope im not). That being said, Does that mean im using my throat and not my diaphragm? If so, how do I make sure Im actually using my diaphragm? And also, when you do sing with your diaphragm, do you flex your abs?
