Chapter 2, Problem 11MIC

Describe what occurs in a dehydration synthesis reaction.

Why are hydrogen bonds relatively weak?

An enzyme accelerates chemical reactions by all of the following, EXCEPT:   a) Bringing reactants close together b) Shifting equilibrium to favor the products c) Adding temporary charges to substrates d) Orienting chemical bonds for best reactivity e) Straining chemical bonds that will be broken

Which of following functional groups are present on this molecule: a) aldehyde b) ketone c) carboxylic acid d) both a and c e) a, b and c O OH

Bromelain is a protease, therefore it breaks down the polymer_______ releasing  monomers as seen above. This is a _________ type of reaction. list of answers: disaccharide sucrose lactose dehydration synthesis nucleotide deoxyribose hydrolysis fructose primary protein glycolipids dipeptide polypeptide amino acid glucose ribose polysaccharide galactose maltose glycoproteins

Draw a “dot & cross” diagram to show the shape of a water molecule (H2O). Bond angles need to be shown. State the shape of a water molecule.

What type of molecule is shown here? Give its biological importance?
