Cell Respiration and Photosynthesis Energy Made by Life

Energy Flow and Chemical Recycling in Ecosystems

SIGNIFICANCE? Cell Respiration The controlled release of energy from organic compounds to form ATP.Photosynthesis The production of organic compounds, including carbohydrates, proteins and lipids, using light enegy and simple inorganic substances such as carbon dioxide and water

What they both have in common… Adenine Triphosphate: Powers most of the cellular work!

Cell Respiration Synthesizing macromolecules such as DNA, RNA and proteins Active transport Moving things around in the cell, such as chromosomes, vesicles, and cell fibers Cells require energy for three main activities:

Glycolysis

Krebs/Citric Cycle

Electron Transport Chain (inside mitochondria) Glycolysis Krebs or Citric Cycle
