BCHM 270 EXAM QUESTIONS WITH ALL ANSWERS REVISED AND UPDATED Carbohydrate digestion - Answer-1) Mouth - Alpha-amylase is released by the salivary glands - Breaks apart starch by cleaving alpha(1 to 4) bonds, leaves smaller branched oligosaccharides as it cannot cleave alpha(1 to 6) bonds - We cannot digest cellulose as we do not have enzymes to cleave beta(1 to 4) bonds) - The enzyme is stopped in the stomach due to the acidic environment 2) Small intestines - Alpha-amylase is released...

The cytochrome b6f complex of the photosynthetic electron transport system is responsible for translocating 8 H+ into the thylakoid space from the stroma. However, a total of 12 H+ accumulate inside the thylakoid space as a result of photon absorption by PSII and PSI. What is the origin of the other 4 H+? correct answers The oxidation of 2 H2O to form O2 + 4 H+ + 4 e- Raffinose-series oligosaccharides are hard for humans to digest because correct answers humans do not have the enzyme necessar...
