i choose answer C

starch is ~25% amylose, ~75% amylopectin

alpha-amylase (dextrinogenic amylase) breaks down amylopectin into small dextrins, limit dextran = end products at which another enzyme must take over to continue the breakdown.. and an hour later, i don't think you'd be at that point

i could be thinking about it too much, but i dont think any nbme is a "joke"

Sometimes questions seem really easy and then when you think about it can get a bit tricky. The "one hour" parameter made me a bit unsure so I posted it.....There was also quite a bit of physiology on the form...lots of graphs and arrows if you know what i mean.....
