Cellular Respiration

Learning Objectives

By the end of this lesson you should be able to:

• Contrast the purpose of aerobic respiration, anaerobic respiration and photosynthesis
• List the main inputs and outputs for the light dependent and light independent stages of photosynthesis
• List the main inputs, outputs and ATP yields for stages of cellular respiration (glycolysis, anaerobic respiration, Kreb’s cycle, electron transport chain in yeast and in animals)

Bonus objectives:

• Easy: Agree it’s ridiculous that life exists given the complexity of reactions it needs (photosynthesis, cellular respiration)
• Challenge: Explain how different factors (temperature, light, glucose availability, carbon dioxide and oxygen concentration) impact the rate of cellular respiration and photosynthesis

🗣️ Cellular Respiration

What this means that what you really need to know is: WHERE, WHAT GOES IN, WHAT COMES OUT and HOW MUCH ATP for each stage. Sooooo … let’s just focus on these aspects.

Overall cellular respiration equation:

Word equation: $$ \text{Oxygen} + \text{Glucose} + \text{ADP} + \text{Inorganic Phosphorus} → \text{Carbon Dixode} + \text{Water} + \text{ATP (avaliable energy)} $$

Chemical equation:

$$ 6O_{2} + C_{6}H_{12}O_{6} + 36ADP + 36P_{i} → 6CO_{2} + 6H_{2}O + 36ATP $$
