notes

1. The opposite of Photosynthesis

2. What is cellular respiration
 The process that uses food and oxygen to produce
energy ( ATP)
 Water and carbon dioxide is formed as byproducts

3. Who or what can undergo cellular
respiration?
 All living organisms can undergo cellular respiration
to produce energy used to drive metabolic
 Some organisms eat plants to obtain food for cellular
respiration
 Other eat other organisms
 Cellular respiration is dependent on photosynthesis

4. The mitochondrion

5. What part of the plant cell or
animal cell is responsible for
cellular respiration?
 Cellular respiration occurs in the mitochondria of
plants cells and animal cells
 The mitochondria are found in the cytoplasm of most
cells
 Mitochondria consist of a double unit membrane.
The outer membrane is oval and the inner
membrane is folded, these enfolding are called
cristae

6. Co-enzymes used during
respiration
 NAD+ -Is a co-enzymes and electron accepter, it
accepts 2 electrons and a hydrogen ion( H+) and
form NADH. NADH can also give of electron and
hydrogen ions to form NAD+ again
 FAD - It is a co-enzymes and electron accepter, it
accepts 2 electrons and 2 hydrogen ions to form
FADH

7. The three stages of cellular
respiration
 Glycolysis
 Critic acid cycle/ Kreb cycle
 Oxidative phosphorylation/ Hydrogen transfer system
