In skin/common_files/customer/main/product tpl it checks if the tabs are on or off.

{if $product_tabs}
{if $show_as_tabs}
{include file="customer/main/ui_tabs.tpl" prefix="product-tabs-" mode="inline" tabs=$product_tabs}
{else}
{foreach from=$product_tabs item=tab key=ind}
{include file=$tab.tpl}
{/foreach}
{/if}
{/if}


That code will then load the tab contents into tabs or not into tabs using those two .tpls
