C3 Cellular Respiration

Question 1

What groups can consumers by classified as?

Answer 1

-Primary consumers: first eater of plants and other producers (herbivore)
-secondary consumers: eats primary consumers
-tertiary consumers: eat secondary consumers
-decomposers: eat waste, return organic and inorganic nutrients to the Earth that can be used again by producers

Question 2

What is ATP (adenosine triphosphate)?

Answer 2

-Useable form of chemical energy
-composed of 5 carbon sugar (ribose), a nitrogen base (adenine), and 3 phosphate molecules
-when energy is required enzymes can extract a phosphate from ATP
-a new products is formed called ADP (adenosine diphosphate): has 2 phosphate molecules and less energy then ATP
-ATP supplies are replenished by phosphorylation which is the addition of a phosphate molecule

Question 3

What is cellular respiration?

Answer 3

-The oxidation of glucose to produce ATP
- each time a hydrogen and electron is removed energy is released
-3 pathways for energy release

Question 4

What is oxidation and reduction?

Answer 4

-Oxidation: occurs when an atom or molecule loses an electron (and hydrogen)
-reduction: occurs when an atom or molecule gains an electron (and hydrogen)

Question 5

What is the most usable source of energy for animals and plants?

Answer 5

-In animals: carbohydrates followed by glycogen, (multiple glucose units), fats then proteins
-in plants: starches then monosaccharides

Question 6

What are the 3 pathways for energy release in cellular respiration?

Answer 6

1. Aerobic respiration (with oxygen)
2. Anaerobic respiration (without oxygen)
3. Fermentation
