How to place product description, reviews,etc in tabs

When a product for sale is selected I notic that the description is under the item is like this

I would like to know how to put the description with optional selections such as reviews and have the customer tab through them like this(image attached)

I thought it was a theme but the item description looked similar regardless of the theme I changed it to,so i figure it had to be configured in marketpress plugin.

Thank you
