What does cellular respiration accomplish?

Answer 1

Definition A series of metabolic processes that take place within a cell in which biochemical energy is harvested fromorganic substance (e.g. glucose) and stored as energy carriers (ATP) for use in energy-requiring activities of the cell. Supplement

Simplified Reaction: C6H12O6 + 6O2 → 6CO2 + 6H2O +energy (ATP)

It consists of:

(1) Glycolysis

(2) Citric Acid cycle or Krebs Cycle

(3) Oxidative phosphorylation

The cell seems to "respire" in a way that it takes in molecular oxygen (as an electron acceptor) and releases carbon dioxide (as an end product), hence, the process is described to be aerobic. There are organisms that use other organic molecules as electron acceptors instead of oxygen. This type of respiration in which oxygen is not used as a final electron acceptor is referred to as anaerobic.

In anaerobic respiration (respiration in absence of oxygen), pyruvate is not metabolized by cellular respiration but undergoes a process of fermentation. The pyruvateis not transported into the mitochondrion, but remains in the cytoplasm, where it is converted to waste products that may be removed from the cell.

Cellular respiration is essential to both eukaryotic and prokaryotic cells since biochemical energy is produced to fuel many metabolic processes, such asbiosynthesis, locomotion, transportation of molecules across membranes.

The entire process occurs in the cytoplasm of prokaryotes. In eukaryotes, glycolysis occurs in the cytoplasm whereas the Krebs Cycle and oxidative phosphorylationin the mitochondrion. Prokaryotic cells can yield a maximum of 38 ATP molecules while eukaryotic cells can yield a maximum of 36.

Answer 2

C6H12O6 > CO2 + H2O + Energy

Glucose to Carbon Dioxide, Water and Energy.


Respiration is the process of producing energy from carbohydrates. It is done in every cell, excluding blood cells.

Answer 3

Cellular respiration is needed in order for the cell to survive. Explained briefly, Cellular respiration involves processes of converting carbohydrates, proteins and fats into ATP, which is energy needed for the cell to function. Without Cellular respiration, life may cease to exist in that particular being.

Answer 4

Cellular respiration takes place in the organelles called mitochondria (singular mitochondrion).

Answer 5

It accomplishes the oxidation of organic compounds that occurs within cells, producing energy for cellular processes.

Answer 6

It provides energy. The formula for respiration is: glucose + oxygen = carbon dioxide + water (+energy). Hope this helps! :)

Answer 7

It provides oxygen

Answer 8

it doesn't
