Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cells use energy for
A
maintaining homeostasis and eliminating wastes
B
transmitting impulses and cellular movement
C
active transport and protein synthesis
D
all of the above
Explanation: 

Detailed explanation-1: -As we have just seen, cells require a constant supply of energy to generate and maintain the biological order that keeps them alive. This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells.

Detailed explanation-2: -Cells require chemical energy for three general types of tasks: to drive metabolic reactions that would not occur automatically; to transport needed substances across membranes; and to do mechanical work, such as moving muscles.

Detailed explanation-3: -Mitochondria play host to one of the most important processes in your body, called cellular respiration. Taking in glucose and oxygen, mitochondria produce energy, which they capture and package as energy-rich molecules of ATP.

Detailed explanation-4: -All cells use chemical energy. is the energy stored in the bonds between atoms of every molecule. To stay alive, cells must be able to release the chemical energy in the bonds. A major energy source for most cells is stored in a sugar molecule called When you need energy, cells release chemical energy from glucose.
