THE DECK

Question 1

Explain how the structure relates to the function for each of the following:
Intermembrane space
Inner membrane
Matrix
Outer membrane
Cristae

Answer 1

Intermembrane space: small spaces to quickly accumulate protons
Inner membrane: contains ATP synthase for oxidiative phosphorylation
Matrix: has appropriate enzymes for the Kerb Cycle
Cistrae: highly folded, increase SA:Vol ratio

Question 2

Define Osmosis and why does it occur?

Answer 2

Osmosis is a process of spontaneous diffusion of water across a semi-permeable membrane. It is order to balance the concentration on both sides of the membrane.

Question 3

Write the balanced chemical equation for photosynthesis?

Answer 3

6CO2 + 6H2O —-> C6H12O6 + 6O2

Question 4

Define Diffusion.

Answer 4

The movement of molecules from high concentration to low concentration.

Question 5

Define Facilitated Diffusion.

Answer 5

Facilitated Diffusion is the transport of substances across a membrane from an area of high concentration to an area of low concentration. Since substances move along a concentrated gradient, chemical energy is not directly needed therefore it is passive transport.

Question 6

Write the balanced chemical equation for cellular respiration?

Answer 6

6CH12O6 + 6O2 —-> 6CO2 + 6H2O
