Question

___________ increases the surface area for mitochondrial activity. *

4 points

(a) Inner membrane

(b) Inter membrane space

(c) Matrix

(d) Cristae​

Answer 1

Answer:

option (A) is correct ... inner membrane...

Explanation:

The folding of the inner membrane increases the surface area inside the organelle, the increased surface area creates more space for reactions to occur. The fluid contained in the mitochondria is called the matrix.

Answer 2

(a) Inner membrane increases the surface area for mitochondrial activity.

Explanation:

• The function of the folds in mitochondria is to increase the surface area.
• Part of cell respiration happens by transferring molecules across the inner membrane so by adding folds a longer piece of membrane can be stuffed inside the mitochondria.
• This membrane is highly convoluted into folds called cristae which act to increase the surface area of this membrane.
• These folds allow for increased surface area in which chemical reactions such as the redox reactions can take place. As the enzymes involved in the ETC are embedded in the inner mitochondrial membrane an increase in surface area through extensive cristae formation could lead to increased rates of respiration.
• The folding of the inner membrane increases the surface area inside the organelle the increased surface area creates more space for reactions to occur.
• The fluid contained in the mitochondria is called the matrix.
• Mitochondria are round tube like organelles that provide energy to a cell in the form of ATP (Adenosine Triphosphate) for performing different chemical activities for the sustainance of life.
