Photosynthesis and Cellular Respiration

Question 1

Photosynthesis

Answer 1

During photosynthesis, plant cells use the energy in sunlight to make glucose from carbon dioxide and water.
Photosynthesis takes place in the chloroplasts of plant cells.
Formula:
6CO²+6H²O+light energy —> C⁶H¹²O⁶+6O²

Question 2

Cellular Respiration

Answer 2

During Cellular Respiration, organisms obtain energy from food.
Cellular Respiration takes place in the mitochondria of animal and plant cells.
Formula:
C⁶H¹²O+6O²—–>6CO²+6H²O+ATP

Question 3

-Extra Card-

Cellular Respiration

Answer 3

In cellular respiration, food(glucose) is broken down into carbon dioxide and water. Energy is released.

Question 4

Energy

Answer 4

Stored in the form of ATP(Adeonosine Triphosphate )

Released as heat to maintain body temperature (homeostasis).

Question 5

Aerobic Respiration

Answer 5

Respiration using oxygen to break food molecules.
¨ Aero ¨ means air, which contains oxygen.
Breaks down glucose and combines broken down products with oxygen, making water and carbon dioxide.

Question 6

Anaerobic Respiration

Answer 6

Low or no oxygen present.
“ An “ in anaerobic means ¨ without ¨
Glucose molecule is only partially broken down, not all of the energy is released.
Fewer ATP molecules are formed.

Question 7

Fermentation

Answer 7

The breakdown of glucose without the use of oxygen.

Question 8

Lactic Acid

Answer 8

Forms in human muscles when there is not enough oxygen to break down glucose, which causes cramping.
