lab # 7 Flashcards
what are the two ways enzymatic activity can be measured?
the amount of substrate consumed and the amount of product produced
what converts the substrate hydrogen peroxide (H2O2) into the products water (H2O) and oxygen (O2)?
catalase
how is catalase activity observed?
monitoring the amount of oxygen bubbles produced
what effects enzyme binding?
pH
what increases the chance of collision, thus making the binding between substrate and enzyme more likely?
faster movement of molecules, caused by increased temperature
what causes enzymes to denature and stop reacting?
too high of temperature
what is a polysaccharide consisting of long chains of glucose?
starch
what is an enzyme found in saliva and pancreatic secretions that breaks down polysaccharides into smaller oligosaccharides and disaccharides such as maltose? and eventually, with time, glucose?
amylase
what is one molecule of sugar and is the building block of carbohydrates?
monosaccharide
what is a disaccharide consisting of two glucose molecules bound together?
maltose
what is a carbohydrate made up of more than two sugar molecules linked together?
oligosaccharide
what is a carbohydrate made up of hundreds to thousands of sugar molecules?
polysaccharide
what does the benedict solution test for?
simple sugars
