CELL STRUCTURE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If the mitochondria in a cell stop functioning correctly, what effect does this have on the whole cell?
A
The cell would not have enough energy to function.
B
The cell would organize itself into tissues more quickly.
C
The nucleus would take over the functions of the mitochondria.
D
Cellular division would increase.
Explanation: 

Detailed explanation-1: -Mitochondrial disease can cause a vast array of health concerns, including fatigue, weakness, metabolic strokes, seizures, cardiomyopathy, arrhythmias, developmental or cognitive disabilities, diabetes mellitus, impairment of hearing, vision, growth, liver, gastrointestinal, or kidney function, and more.

Detailed explanation-2: -If your mitochondria are not working properly then you are less able to convert food into ATP. For cells that require a lot of ATP, for example your muscles, this is a problem and they may become weaker and get tired faster.

Detailed explanation-3: -Mitochondrial dysfunction occurs when the mitochondria don’t work as well as they should due to another disease or condition. Many conditions can lead to secondary mitochondrial dysfunction and affect other diseases, including: Alzheimer’s disease. Muscular dystrophy.

Detailed explanation-4: -Without mitochondria, present-day animal cells would be dependent on anaerobic glycolysis for all of their ATP. When glucose is converted to pyruvate by glycolysis, only a very small fraction of the total free energy potentially available from the glucose is released.
