Study Notes

Biochemistry Overview

  • Biochemistry is the branch of science that examines the chemical and physical processes in living organisms.
  • It combines principles from biology and chemistry to understand life's molecular mechanisms.

Definition and Scope

  • Biochemistry is defined as the study of the chemical substances and vital processes occurring in living organisms.
  • It aims to dissect biological functions at a molecular level, thus bridging chemistry and biology.

Tools and Methods

  • Biochemists employ various techniques to study biological processes, including molecular biology methods, spectroscopy, and chromatography.
  • These tools help explain complex biological phenomena by analyzing their molecular components and interactions.

Principles of Biochemistry

  • Basic principles of biochemistry are commonly found across all living organisms, indicating universal metabolic pathways.
  • These principles include enzyme activity, genetic information flow, and cellular structure functions.

Cosmological Context

  • According to the Big Bang theory, the universe is approximately 13.8 billion years old.
  • This theory posits that the universe originated from an extremely hot and dense state, leading to its expansion and subsequent cooling.
