Photosynthesis & Cellular Respiration (Ch. 9, 10)

Question 1

What is the process of changing solar energy into food energy called?

Answer 1

photosyntehsis

Question 2

What is the main energy-trapping molecule in plants called?

Answer 2

chlorophyll

Question 3

What are the chemical equations of photosynthesis and cellular respiration?

Answer 3

6co2+6H20 -> C6H12O6 + 602 (P)
C6H12O6 + 602 -> 6CO2 + 6H20 + ATP (CR)

Question 4

Describe the structures of mitochondria and chloroplasts

Answer 4

mitochondria: double membraned, rod shaped structure
chloroplasts: oval shaped, double membrane

Question 5

What are the two types of anaerobic respiration?

Answer 5

alcohol & lactic acid - fermentation

Question 6

What is produced when your muscles feel tired after long exercises?

Answer 6

lactic acid

Question 7

What is the purpose of cellular respiration?

Answer 7

makes ATP by breaking down sugars

Question 8

What is glycolysis?

Answer 8

the breakdown of glucose 6-c glucose -> 3c pyruvates

Question 9

What is ATP? How is energy released from ATP?

Answer 9

ATP is the energy molecule most cells use for cellular processes
- adenine
- ribose sugar
- 3 phosphate groups
Energy is released from ATP from the breakdown of food to cell.
