Photosynthesis & Cellular Respiration
Energy & Living Things, Photosynthesis and Cellular Respiration

2. Energy in Living Things
Chloroplast contain chlorophyll
Chlorophyll
a pigmentation

3. Energy in Living Things
Building Molecules That Store Energy
Metabolism: builds and breaks molecules
Photosynthesis: conversion of light energy into chemical energy
Photo = LIGHT (think photos need it)
Synthesis = BUILD/CREATE

4. Energy in Living Things
Autotrophs: organisms that use sunlight or inorganic molecules to produce organic matter
These organisms include:
Plants – use sunlight
Prokaryotes – use chemicals flowing out of earth vents on the ocean floor

5. Photosynthesis All energy used by organisms is traced back to the sun
The type of energy used for storing that converted light energy IS:
ATP

6. ATP

7. Photosynthesis
Chemical Equation:

9. Factors That Affect Photosynthesis
Increase
Light Intensity Increases (until saturation)
Carbon Dioxide concentration (until max)
Decrease
Lowered or no amounts of carbon dioxide

10. Breaking Down Food for Energy
Cellular respiration: releases energy that is contained in food to convert it to ATP (another form of energy)
ATP is the source of energy for cells to carry out their daily activities for an organism to survive

11. Cellular Respiration – Cellular Energy
Equation of Cellular Respiration:

12. Cellular Respiration – Aerobic
Aerobic: metabolic processes that require O2

13. Cellular Respiration – Anaerobic
Anaerobic: metabolic processes that do not require O2
