• Aerobic respiration occurs during the day, while anaerobic respiration occurs at night.
• The difference is in the color of the cells.
• The main difference is the requirement of oxygen.

7.3 Cellular Respiration

Overview of Cellular Respiration

●Organisms obtain energy in a process called cellular
respiration.

●Respiration harvests electrons from organic molecules
and uses the energy to make ATP.

●The equation for cellular respiration is the opposite of
the equation for photosynthesis:

Overview of Cellular Respiration

●Cellular respiration occurs in two main parts: glycolysis and
aerobic respiration.
○Glycolysis is an anaerobic process, meaning it does not
require oxygen.

○Aerobic respiration involves the Krebs cycle and
electron transport.

○Aerobic processes require oxygen.

Glycolysis

●Glucose is broken down in the
cytoplasm through the process of
glycolysis.

●Two molecules of ATP and two
molecules of NADH are formed for
each molecule of glucose that is
broken down.

Multiple Choice

Which stage of cellular respiration does NOT require oxygen?

• Glycolysis
• Pyruvate oxidation
• Electron transport chain
• Krebs cycle

Multiple Choice

What molecule does cellular respiration use to store energy?

• Guanosine triphosphate (GTP)
• Adenosine triphosphate (ATP)
• Cytidine triphosphate (CTP)
• Uridine triphosphate (UTP)
