sequence determines the structure of a protein. This is determined by the codons in DNA and m. structure refers to one of two shapes that a polypeptide may take: beta- or alpha . This is determined by bonding. structure is the further folding of the polypeptide on itself. The polypeptide begins to form a more complex, unique, three-dimensional shape. Finally, structure - which does not apply to all proteins - is the interaction between several polypeptides to form a globular protein, one common example being , responsible for carrying oxygen.

Question 9 of 11

1

Select from the dropdown lists to complete the text.

( Haemoglobin, Elastin, Keratin, Collagen ) is a ( functional, structural ), ( globular, fibrous ) protein with a ( quaternary, primary, secondary, tertiary ) structure consisting of ( four, three, two, five ) polypeptide sub-units. It also has a ( prosthetic group, carboxyl group, active site ), which is essential to its purpose of carrying ( oxygen, cells, glucose, insulin ) around the body.

True
False

Explanation

Question 11 of 11

1

Select from the dropdown lists to complete the text.

The role of insulin is to regulate ( glucose, cholesterol, water, hydrogen ion ) concentration in the blood. It does this by binding to a ( specific, nonspecific ) target receptor, which triggers the ( uptake, release, synthesis ) of ( glucose, cholesterol, water, ATP ) into cells and the metabolism of ( glucose, cholesterol, glycogen, triglycerides ) in ( respiration, photosynthesis, glycogenesis, glucogenesis ). The overall effect is a ( decrease, increase ) in blood ( glucose, cholesterol, water, hydrogen ions ) concentration.
