Questions and Answers

1.

Structural biology is the branch of ________________.
- A.
  
  Art
- B.
  
  Biochemistry
- C.
  
  History
- D.
  
  Drama
Correct Answer
B. Biochemistry

Explanation
Structural biology is the branch of biochemistry because it focuses on studying the structure and function of biological macromolecules, such as proteins, nucleic acids, and carbohydrates. This field combines techniques from biology, chemistry, and physics to understand how the three-dimensional structure of these molecules relates to their biological activity. By studying the structure of these molecules, researchers can gain insights into their functions, interactions, and potential therapeutic targets.

Structural biology is concerned with the molecular structure of ______________.
- A.
  
  Life
- B.
  
  Macromolecules
- C.
  
  Physics
- D.
  
  Biology
Correct Answer
B. Macromolecules

Explanation
Structural biology is a field that focuses on studying the molecular structure of macromolecules. Macromolecules are large and complex molecules that are essential for various biological processes. By understanding their structure, scientists can gain insights into their functions and mechanisms, which can be crucial for developing new drugs and therapies. Therefore, macromolecules are the main subject of study in structural biology.

Alterations in structures affect _________________.
- A.
  
  Form
- B.
  
  Life
- C.
  
  Functions
- D.
  
  Works
Correct Answer
C. Functions

Explanation
Alterations in structures can have a direct impact on the functions of a system or organism. When the structure of something changes, it can lead to changes in how that thing operates or performs its intended tasks. For example, if the structure of a protein is altered, it may no longer be able to carry out its specific function in the body. Therefore, alterations in structures can affect the functions of the system or organism.

Which is a method of determining the structure of biomolecules?
- A.
  
  Enlargement
- B.
  
  Staining
- C.
  
  Proteolysis
- D.
  
  Writing
Correct Answer
C. Proteolysis

Explanation
Proteolysis is a method of determining the structure of biomolecules. It involves the enzymatic breakdown of proteins into smaller fragments, allowing for the identification and characterization of their amino acid sequences. This technique is commonly used in protein research and structural biology to gain insights into the composition and organization of biomolecules.

Name the oxygen-transporting protein found in red blood cells.
- A.
  
  Wbc
- B.
  
  Dna
- C.
  
  Gene
- D.
  
  Hemoglobin
Correct Answer
D. Hemoglobin

Explanation
Hemoglobin is the correct answer because it is the oxygen-transporting protein found in red blood cells. It binds to oxygen in the lungs and carries it to the body's tissues, ensuring that oxygen is delivered to where it is needed. Hemoglobin also helps in the transport of carbon dioxide, a waste product, from the tissues back to the lungs for exhalation. This protein is essential for the proper functioning of the respiratory system and plays a crucial role in maintaining the body's oxygen balance.

An analytical technique that sorts ions based on their mass to charge ratio is called ___________________.
- A.
  
  Abstract
- B.
  
  Ionization
- C.
  
  Mass spectrometry
- D.
  
  Chagrin
Correct Answer
C. Mass spectrometry

Explanation
Mass spectrometry is an analytical technique that sorts ions based on their mass to charge ratio. It involves the ionization of molecules, followed by the separation and detection of the resulting ions. By measuring the mass to charge ratio of ions, mass spectrometry can provide valuable information about the composition, structure, and abundance of molecules in a sample.

Which is a biological macromolecule?
- A.
  
  Organic
- B.
  
  Acid
- C.
  
  Nucleic acid
- D.
  
  Base
Correct Answer
C. Nucleic acid

Explanation
Nucleic acid is a biological macromolecule. It is composed of nucleotides and plays a crucial role in storing and transmitting genetic information. Nucleic acids include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), which are essential for the functioning and development of all living organisms.

Which is a biological macromolecule?
- A.
  
  Amino acid
- B.
  
  Salt
- C.
  
  Sand
- D.
  
  Ion
Correct Answer
A. Amino acid

Explanation
An amino acid is a biological macromolecule because it is a building block of proteins, which are essential macromolecules in living organisms. Proteins perform a wide range of functions in the body, including structural support, enzymatic activity, and cell signaling. Amino acids are linked together through peptide bonds to form polypeptide chains, which then fold into functional proteins. In contrast, salt, sand, and ion are not biological macromolecules but rather inorganic substances or particles.

A structure is an arrangement of _________________.
- A.
  
  Ions
- B.
  
  Places
- C.
  
  Structures
- D.

A structure could also be termed as ________________.
- A.
  
  Erect
- B.
  
  Organization
- C.
  
  Construction
- D.
  
  Heading
Correct Answer
B. Organization

Explanation
A structure could also be termed as an organization because both terms refer to a system or arrangement that is designed to achieve specific goals or objectives. Just like an organization, a structure has various components or elements that work together in a coordinated manner to fulfill its purpose. Additionally, both terms imply a sense of order, hierarchy, and purposeful design. Therefore, it is appropriate to describe a structure as an organization.
