After the water content of a cell evaporates, what is the remaining mass called?

Which set of elements is primarily involved in the synthesis of biomolecules?

Introduction to Biochemistry

Biochemistry is a branch of biology that explains the biochemical basis of life
It provides information about all processes in living organisms, from body structure to DNA for enzyme/protein synthesis
It explains abnormal mechanisms linked to diseases, opening doors for medicine development
Biochemistry helps investigate challenging biological problems like organ formation, cell growth, and memory mechanisms

Chemical Composition of Cells

Living organisms are made of cells and tissues, which are composed of molecules (chemically bonded atoms)
Cell structure and function depend on chemical composition
Studying chemical composition is crucial for understanding cell functions and metabolism

Chemical Composition of Cells (Details)

Living organisms are made of cells that contain protoplasm (living substance)
Protoplasm's chemical composition is approximately 70-90% water
Removal of water leaves a "dry weight", containing large organic molecules called biomolecules
Biomolecules are compounds created by living organisms, primarily made from carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur
Biomolecules constitute about 98% of the total biomolecules

Explore the fundamentals of biochemistry, a crucial branch of biology that delves into the biochemical basis of life. This quiz covers the chemical composition of cells and their significance in understanding cellular functions and metabolism. Gain insights into how biochemical processes relate to health and disease.
