Biomolecules Quiz

Elements of Human Body Mass

• Oxygen, carbon, hydrogen, and nitrogen constitute 96% of the human body's mass.
• Oxygen accounts for approximately 65% of body mass, followed by carbon at about 18%, hydrogen at 10%, and nitrogen at 3%.

Primary Metabolites

• Primary metabolites are compounds directly involved in growth and development, such as amino acids, sugars, and fatty acids.
• An example would be glucose, which serves as a primary energy source in cellular respiration.

Essential Biological Molecules

• Biomolecules that are essential to biological processes are referred to as metabolites.
• These include both primary metabolites for basic physiological functions and secondary metabolites that play roles in plant defense and signaling.

Subfields Studying Biomolecules

• Biochemistry focuses on the chemical processes and substances within living organisms.
• Molecular biology examines the interactions between various cellular systems, including DNA, RNA, and proteins.

Small Biomolecules Examples

• Small biomolecules include amino acids, nucleotides, and simple sugars.
• These molecules serve as building blocks for larger macromolecules such as proteins, nucleic acids, and polysaccharides, influencing numerous metabolic pathways.
