Cisco 3750x switch with added 4 x Gig fiber card

Greetings,
I have several 3750x series switches with an add on card that has 4 gig fiber ports. The card shows slot gi1/1/1 as a 1 gig fiber, slot gi1/1/2 as a 1 or 10 gig fiber, slot 1/1/3 as a 1 gig fiber and slot gi1/1/4 as a 1 or 10 gig fiber. My question is, can I use all 4 ports?

I am planning a build out of some fiber, but if I am wondering if I use the two 10 gig ports as 10 gig ports, will that make the two 1 gig ports unavailable?

Ideally, I want to use gi1/1/1 as a 1 gig port and gi1/1/2 as a 10 gig and gi1/1/3 as a 1 gig and gi1/1/4 as a 10gig. Will this work?

Thanks.

They work in pairs, either you go 2 10Gig or 4 1Gig. You can also go, 1 10Gig and 2 1Gig.

The module has four slots. Two slots support only 1-Gigabit SFP modules. Two slots support either 1-Gigabit SFP or 10-Gigabit SFP+ modules.
 
Note The GLC-T SFP is not supported on the SFP+ slots of C3KX-NM-10G.

The four slots are grouped as two pairs, with each pair consisting of one SFP slot and one SFP+ slot. Each pair supports either two 1-Gigabit SFP modules or one 10-Gigabit SFP+ module. A 10-Gigabit SFP+ module cannot operate at the same time as the corresponding 1-Gigabit SFP module in the pair.
