In a hypothetical disease, the inner membrane of mitochondria does not fold intofinger-like projections. Illustrate what will happen to the cells of the body.

The inner membrane of mitochondria folds into finger-like projections known as cristae. These cristae increase the surface area of the mitochondria, allowing for a higher number of chemical reactions to occur simultaneously. This is particularly important for the process of cellular respiration, where glucose is converted into ATP, the energy currency of the cell.

1. Reduced ATP Production: If the inner membrane of the mitochondria does not fold into cristae, the surface area of the mitochondria would be significantly reduced. This would limit the number of chemical reactions that could occur at the same time, leading to a decrease in the production of ATP.

2. Energy Deficiency: ATP is crucial for many cellular processes, including muscle contraction, nerve impulse propagation, and chemical synthesis. A decrease in ATP production would therefore lead to an energy deficiency in the cells.

3. Impaired Cellular Functions: This energy deficiency could impair many cellular functions. For example, muscle cells may not be able to contract properly, leading to muscle weakness. Similarly, nerve cells may not be able to propagate impulses effectively, potentially leading to neurological symptoms.

4. Cell Death: In severe cases, the energy deficiency could lead to cell death. This is because ATP is needed for the active transport of substances across the cell membrane, a process that is vital for cell survival.

5. Organ Failure: If a large number of cells in an organ die, it could lead to organ failure. For example, if a large number of heart muscle cells die, it could lead to heart failure.

In conclusion, if the inner membrane of mitochondria does not fold into cristae, it could have severe consequences for the cells of the body, potentially leading to organ failure and death.
