Lab exam (Cellular Repiration)

Physical process of inhaling O₂ and exhaling CO₂ using the lungs.

Difference between breathing and respiring (Breathing): 

Biochemical process inside cells that uses O₂ to break down glucose and make ATP (energy).

Difference between breathing and respiring (Respiring)

Provides ATP, which powers all cellular processes—movement, transport, metabolism, growth

Why is Cellular Respiration important?:

C6​H12​O6​+6O2​→6CO2​+6H2​O+ATP

What is the chemical equation that occurs during respiration?: 

Glucose (C₆H₁₂O₆) + Oxygen (O₂)

What are reactants?:

Carbon dioxide (CO₂) + Water (H₂O) + ATP energy

What are products?: 

Cellular Respiration

The process by which cells break down glucose in the presence of oxygen to produce ATP, carbon dioxide, and water.

Usually measured by CO₂ production or O₂ consumption using respirometers or gas sensors

How did we measure respiration?:

Faster respiration (enzymes work faster).

How did temperature affect the experiment?

(Higher temperature):

Slower respiration (enzymes work slower).

How did temperature affect the experiment?

(Lower temperature):
