These proteins function like revolving doors or turnstiles, but with a twist: they change shape to shepherd molecules through. The process can be visualized in three distinct stages:
There are two main types of active transport: explain the process of active transport
This is where comes in. It is the cellular equivalent of walking uphill; it requires effort, specialized machinery, and, most importantly, fuel. What is Active Transport? These proteins function like revolving doors or turnstiles,
This is the reverse. A vesicle inside the cell fuses with the membrane to expel waste or secrete hormones and enzymes into the external environment. Why Does It Matter? it requires effort
