Biochemistry Basics

What is biochemistry?

• The study of chemical processes in non-living organisms.

• The study of physical processes in living organisms.

• The study of biological processes in non-living organisms.

• The study of chemical processes in living organisms.

Why is biochemistry important in the field of medicine?

• Biochemistry is important in the field of medicine because it helps us understand the chemical processes and reactions that occur in living organisms.

• Biochemistry is not important in the field of medicine.

• Biochemistry only focuses on non-living organisms.

• Chemical processes and reactions have no relevance in medicine.

What are the different branches of biochemistry?

• organic chemistry, inorganic chemistry, physical chemistry

• structural biochemistry, enzymology, metabolism, molecular biology, and genetics

• pharmacology, toxicology, medicinal chemistry

• cell biology, microbiology, immunology

What is the chemical composition of living organisms?

• carbon, hydrogen, nitrogen, oxygen, phosphorus, and calcium

• carbon, hydrogen, nitrogen, oxygen, phosphorus, and iron

• carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur

• carbon, hydrogen, nitrogen, oxygen, phosphorus, and selenium

How do carbohydrates contribute to the chemical composition of living organisms?

• Carbohydrates are primarily used for storage, not as a source of energy.

• Carbohydrates are only found in plants, not in animals.

• Carbohydrates have no role in the chemical composition of living organisms.

• Carbohydrates provide energy and serve as structural components.

What role do lipids play in the chemical composition of living organisms?

• Lipids are only found in animal cells and have no role in plant cells.

• Lipids are primarily used for structural support in the body.

• Lipids are only used for energy storage and have no other functions.

• Lipids are a major component of cell membranes and provide energy storage, insulation, and signaling molecules.

How do proteins contribute to the chemical composition of living organisms?

• Proteins serve various functions in living organisms.

• Proteins have no role in the chemical composition of living organisms.

• Proteins are only found in non-living organisms.

• Proteins are made up of inorganic molecules.

What are nucleic acids and how do they contribute to the chemical composition of living organisms?

• Nucleic acids are proteins that regulate cellular processes in living organisms.

• Nucleic acids are carbohydrates that provide structural support to living organisms.

• Nucleic acids are small molecules that provide energy to living organisms.

• Nucleic acids are macromolecules that store and transmit genetic information in living organisms.

What is the scope of biochemistry in the field of agriculture?

• Biochemistry helps in understanding plant metabolism, nutrient uptake, and the development of new agricultural practices and technologies.

• Biochemistry is only useful for studying diseases in plants and has no impact on agricultural practices.

• Biochemistry has no relevance in the field of agriculture.

• Biochemistry only focuses on animal metabolism and has no application in agriculture.

How does biochemistry contribute to the study of genetics?

• Biochemistry provides insights into the chemical processes and molecules involved in genetic inheritance and gene expression.

• Biochemistry is only useful for studying non-genetic processes.

• Biochemistry only focuses on the physical structure of genes, not their function.

• Biochemistry has no relevance to the study of genetics.
