Chemicals of Life & Biological Life

Cells and Energy Production

• Cells do not directly produce energy.

  • They create glucose, which contains energy.

  • This glucose is synthesized from energy obtained from external sources.

Role of Photosynthesis

• Photosynthesis is a critical process that allows cells to convert sunlight into chemical energy.

  • It converts carbon dioxide and water into glucose using light energy.

  • The energy captured during photosynthesis is stored in the bonds of glucose, which can be used by the cell later.

Periodic Table Overview

• The periodic table consists of all known chemical elements.

  • Displays elemental properties and relationships between elements.

  • Elements are arranged in order of increasing atomic number.

Importance in Biological Processes

• The periodic table is significant for understanding the elements that make up biological molecules.

  • Elements such as carbon, hydrogen, oxygen, and nitrogen are fundamental to life.

  • Other elements from the table are crucial in various biochemical reactions.
