Quiz 2 Answers Biochem
1.) The most abundant protein in the human body is:
Collagen
2.) Collagen is NOT a regular component in:
Red blood cells
Basement membranes
Ligaments
Cornea (eye)
3.) Scurvy, the collagen disease, is NOT:
Associated with proline hydroxylating enzyme deficiency
Associated with lysine hydroxylating enzyme deficiency
Due to vitamin C deficiency
Hereditary disorder
4.) Metabolic pathways are carried out in specific locations in a cell, and as
follows, EXCEPT:
Complex macromolecules are degraded in lysosomes
Glycolysis takes place in the cytosol
Proteins are synthesized in lysosomes
DNA synthesis is carried out in the nucleus of the cell
5.) To use an enzyme or a set of enzymes in the blood for the diagnosis of a liver
disease includes the followings, EXCEPT:
The enzymes selected need to be specific for hepatic tissue
The assumption is that enzymes are not present in tissues other than liver
The blood levels of these enzymes must be normally elevated
The enzyme would preferably be measurable in the laboratory in routine work
6.) Network forming collagen is found in
Basement membranes
7.) For tropoelastin to become elastin, it needs to interact with:
Fibrillin
8.) The following statement is NOT true about osteogenesis imperfect
Due to the reduced production of alpha and beta collagen chains
Bones are easily bendable and fracture easy
The spines are not affected in this disorder
It has dramatic effects on wound healing
9.) The following statements about anti-trypsin activity in the lung are true,
EXCEPT
- Tobacco smoking enhances anti-trypsin activity in the lung
Document Summary
The most abundant protein in the human body is: Metabolic pathways are carried out in specific locations in a cell, and as follows, except: Dna synthesis is carried out in the nucleus of the cell. To use an enzyme or a set of enzymes in the blood for the diagnosis of a liver disease includes the followings, except: The enzymes selected need to be specific for hepatic tissue. The assumption is that enzymes are not present in tissues other than liver. The blood levels of these enzymes must be normally elevated. The enzyme would preferably be measurable in the laboratory in routine work. For tropoelastin to become elastin, it needs to interact with: The following statement is not true about osteogenesis imperfect. Due to the reduced production of alpha and beta collagen chains. The spines are not affected in this disorder. The following statements about anti-trypsin activity in the lung are true, Tobacco smoking enhances anti-trypsin activity in the lung.
