A carbohydrate with an aldehyde functional group is called:
1 answer:
Answer: The correct answer is Aldose.
- A disaccharide is produced when two monosaccharides are linked by a glycosidic bond.
- Any carbohydrate which has six carbon atoms is called as hexose. It is a monosaccharide. The functional group in hexose can be aldehyde or ketone.
- Ketose is a carbohydrate which contains ketone as a functional group.
Aldose, as the name suggests, it means having aldehyde group. Thus, it is a carbohydrate which has aldehyde as a functional group.
Example- D- Glyceraldehyde.

Answer:
a. True
b. True
c. False
d. True
Explanation:
a). A a very low substrate concentration , . Thus according to the Machaelis-Menten equation becomes
Here since the varies directly to the substrate concentration [S], the initial velocity is lower than the maximal velocity. Thus option (a) is true.
b). The Michaelis -Menten kinetics equation states that :
Here the initial velocity changes directly with the substrate concentration as is directly proportional to [S]. But
is same for any particular concentration of the enzymes. Thus, option (b) is true.
c). As the substrate concentration increases, the initial velocity also increases. Thus option (c) is false.
d). Option (d) explains the procedures to estimate the initial velocity which is correct. Thus, option (d) is true.
