Subject: Can chemoautotrophic organisms produce sugars?

I got into a little discussion with my AP Bio teacher here 
who was trying to describe different ways of aquiring energy and thus 
also had to describe chemoautotrophic organisms. Well, an he postulated 
that "Chemosynthesis" had two steps:

1. energy conversion

2. substance conversion

He correctly taught us that in step one, inorganic compounds such 
as H2S are oxidized to gain energy in form of ATP (And NADH H+). Well, I 
agreed that this would agree with substrate level phosphorilization.
BUT he described the second point as analogous to the Calvin 
cylce in PHOTOAUTOTROPIC organisms. In which CO2 and other compounds by 
the means of ATP, NADPH H+ produce glucose or sugars from which that 
organism is living on.

So my question now is:

1. Do chemoautotrophic organisms have the ability to produce 
simple sugars to store energy? (Because I thought that these early 
Prokaryotes haven't developed such metabolic pathways yet.)

2. Their carbon sourcer is CO2. But they don't incorporate this 
CO2 into sugars, like photoautotrophic organisms do. They simply live from 
the ATP gained by oxidative phosphorylization of inorganic compunds. 
Is this correct?

If by any chance you should have further information on 
"Chemosynthesis" I'd be glad if you could help me out on that one, too. Our 
teacher gave us this definition:

Autotrophic assimilation of some "colorless" (obviously he is 
referring to organisms not capable of performing Photosynthesis) bacteria. 
Gain energy by the means of oxidation of anorganic compounds.
1. Energy Conversion
2. Substance Conversion
( don't ask me about that one, I think he tried to explain that 
some organisms gain their energy from some inorganic compounds and also 
are able to change them as a metabolic sideproduct (such as purple 
sulfur bacteria do sometimes.).

This sounds quite alright with me but I don't agree with his 
analogy of point 2. with the calvin cycle of photoautotrophic organisms.

I'd be glad if you could shed some new light on this matter, 
please. We would both like to hear another opinion about our discussion.

What I could get out of the Campbell textbook has helped me a 
little but didn't answer my questions fully, that's why I thought I ask you. 
The only relevant information from the Campbell book I could spot on 
page 505 where all the kinds of nutrition and means of energy 
aquisition are listed and explained.
