250+ TOP MCQs on Synthetic Polymers for Biomaterial Processing and Answers

Tissue Engineering Questions and Answers for Experienced people focuses on “Synthetic Polymers for Biomaterial Processing”.

1. ____________ polymers are those which are human-made polymers.
A. Hydrogel
B. Biodegradable
C. Natural
D. Synthetic
Answer: D
Clarification: Synthetic polymers are those which are human-made polymers. Polymers are those which consist of repeated structural units known as monomers. E.g., polythene has ethene as a monomeric unit.

2. Synthetic polymers are sometimes referred as __________
A. plastics
B. metals
C. ceramic
D. jelly
Answer: A
Clarification: Synthetic polymers are sometimes referred as “plastics”, of which the well-known ones are nylon and polyethylene. The polymers which are formed by linking monomer units, without the any change of material, are known to as addition polymers or also called as chain-growth polymers. All these are sa to be synthetic polymers.

3. Non-biodegradable- Synthetic polymers are made from _____________
A. petroleum
B. lips
C. carbohydrates
D. proteins
Answer: A
Clarification: Many polymers that are commonly found in households are non-degradable as they are petroleum based polymers. In order to control the environmental issues arising due to these polymers, bioplastics have been introduced as an alternative, these are biodegradable in nature.

4. Synthetic materials owing to the bioactive properties have better interactions with the cells which allow them to enhance the cells’ performance in a biological system.
A. TRUE
B. FALSE
Answer: B
Clarification: Natural materials owing to the bioactive properties have better interactions with the cells which allow them to enhance the performance of the cell in a biological system. Synthetic biomaterial guance proved by biomaterials may facilitate the restoration of the structure and function of damaged or diseased tissues.

5. Which of the following is an example of Synthetic polymer?
A. Polylactic ac
B. Dextran
C. Chitin
D. Amylose
Answer: A
Clarification: Polylactic ac is an example of synthetic polymers. Dextran, chitin and amylose are examples of natural polymers.

6. Polyesters are a kind of Natural polymer.
A. TRUE
B. FALSE
Answer: B
Clarification: Polyesters are the largest family of synthetic materials under study. The most commonly used polyesters are poly (lactic ac. (PLA., poly (α-hydroxy acs), poly (glycolic ac. (PGA. etc.

7. Synthetic polymers can be manufactured with additional chemical functional groups to induce tissue regeneration.
A. TRUE
B. FALSE
Answer: A
Clarification: Synthetic polymers are attractive because they can be fabricated into various shapes. Synthetic polymers can be manufactured with additional chemical functional groups to induce tissue regeneration.

8. The following is the monomer for ___________

A. Poly (lactic ac.
B. Poly (glycolic ac.
C. Polythene
D. Polystyrene
Answer: B
Clarification: The monomer for poly (lactic ac. is (OCH(CH₃)CO). The monomer for poly (glycolic ac. is (OCH₂CO). The monomer for polythene is (CH₂CH₂). The monomer for polystyrene is (C₈H₈).

9. Polylactes are non-biodegradable in nature.
A. TRUE
B. FALSE
Answer: B
Clarification: Generally, the degradation of polylactes involves random hydrolysis of the ester bonds. Poly (lactic ac. degrades to form lactic ac which is normally present in the body.
