Answer
The coldest temperature is absolute zero (0 Kelvin or -273.15°C).
Solution
a
Absolute zero is the theoretical temperature at which all molecular motion ceases. It is defined as 0 Kelvin or -273.15°C
Key Concept
Absolute zero
Explanation
Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance.
Answer
The function of mitochondria during cellular metabolism is to produce ATP through oxidative phosphorylation.
Solution
a
Mitochondria are known as the powerhouses of the cell because they generate most of the cell's supply of ATP, which is used as a source of chemical energy
b
During cellular respiration, mitochondria convert energy stored in glucose into ATP through a process called oxidative phosphorylation
Key Concept
Mitochondria and ATP production
Explanation
Mitochondria play a crucial role in cellular metabolism by converting energy from nutrients into ATP, the energy currency of the cell, through oxidative phosphorylation.
