Respiration

Question 1

General equation for respiration is…?

Answer 1

enzymes
Glucose + Oxygen ————–> ATP + Carbon dioxide + Water
- C(6)H(12)O(2) + O(2) ——> ATP + CO(2) + H(2)O -

Question 2

What is the main job of respiration?

Answer 2

As glucose cannot be used directly, it is change into a chemical that cells can get energy from called ADENOSINE TRIPHOSPHATE (ATP).

Question 3

(3 phosphates)(tri)
Adenosine——-P——-P-/-/-P
^——High energy bond.

Answer 3

Diagram of ATP

Question 4

Adenosine——-P——-P (ENERGY!) —–> P

Answer 4

As energy is used in our cells, energy is released, the high energy bond is broken and end up with ADP (ADENOSINE DIPHOSPHATE)

Question 5

What are some examples of energy consuming reactions?

Answer 5

Muscular contractions
Cell division
Protein synthesis

Question 6

How does Glycosis occur?

Answer 6

It occurs in the cytoplasm and does not require oxygen

Question 7

Glucose (6C)
|
| / 2x ADP + 2Pi
| /____> 2 ATP (a small quantity of
/\ energy released)
/ \
/ \
pyruvate pyruvate
(3C) (3C)

What happens next is dependent on the availability of oxygen to the cell…

Answer 7

…Plenty of Oxygen…Aerobic respiration.
…Little/no Oxygen…Fermentation
