I presume you are referring to human's cellular respiration and not bacterial cellular respiration.

With human's cellular respiration, you first have to understand that our body uses ATP (short for adenosine triphosphate) as the main source of fuel. It is ATP that helps our body to repair itself, to grow, and to eliminate basic toxins such as carbon dioxide. Second, the main source of ATP is glucose from breakdown of the food we eat.

With that in mind, cellular respiration (also known as aerobic respiration) is the use of inhaled oxygen to more efficiently make ATP. With oxygen/ aerobic respiration, a cell's mitochondria power house can make 36 ATPs from one molecule of glucose via glycolysis + Kreb cycle + electron transfer chain pathway. Whereas without oxygen (aka anaerobic respiration), a cell stops at glycolysis making only 2 ATPs.

As you can see, 36 vs. 2 ATPs is a big difference. A cell that is metabolically active and requires a lot of ATPs such as the neurons (brain cells), the myocardiocytes (heart cells), and the proximal tubule cells (kidney cells) will die off when the glucose supply is depleted from inefficient breakdown to produce ATPs.

So in short, without cellular respiration, a cell will use anaerobic respiration, making 1/16 of normal ATPs, survive for 2 mins to hours (depending on the cellular activities and body temperature) then die off due to depletion of glucose source within the cell or die off due to activation of Fas self-suicide mechanism.

Hope this answers your question. =)

Where does Cellular Respiration happen?

Cellular respiration takes place in the mitochondria of the cell. It is the process where cells convert glucose into ATP (energy) through a series of biochemical reactions.


What is the process that does the opposite to photosynthesis?

The process that is the opposite of photosynthesis is cellular respiration. In cellular respiration, organisms break down glucose to produce energy, carbon dioxide, and water. This process releases energy stored in glucose and is used by all living organisms to power their cellular functions.


How is anaerobic respiration different from cellular respiration?

Anaerobic respiration does not require oxygen, while cellular respiration does. Anaerobic respiration produces less energy compared to cellular respiration.


What are some important questions to ask about cellular respiration?

Some important questions to ask about cellular respiration include: How does cellular respiration produce energy for cells? What are the different stages of cellular respiration and how do they work? What role do mitochondria play in cellular respiration? How is cellular respiration related to the process of photosynthesis? What factors can affect the efficiency of cellular respiration in cells?


How would a loss of chlorophyll affect cellular respiration in plant cells?

A loss of chlorophyll in plant cells would reduce the amount of glucose produced through photosynthesis, which is a crucial energy source for cellular respiration. This would result in a decrease in the amount of substrate available for cellular respiration to produce ATP, impacting the overall energy production of the cell.
