1. A peptide is best described as:

A chain of amino acidsA liquid measurementA syringe typeA mineral

2. What gives a peptide much of its biological specificity?

Its amino-acid sequence and three-dimensional shapeThe colour of the vialThe number of mL in a syringeThe brand name alone

3. Many peptides function biologically as:

Signals that bind to receptors or influence cellular pathwaysOnly structural mineralsOnly energy-storage moleculesOnly digestive enzymes

4. Why are peptides researched across such different goals?

Different peptides can influence different signalling systemsEvery peptide has exactly the same targetAll peptides only affect appetiteAll peptides only affect skin

5. Which statement is most accurate?

The word peptide tells you the exact effectYou need to know the specific peptide and its target to understand what it may doAll peptides are interchangeableAll peptides are proteins of the same size
