Cellular respiration produces energy in the form of ATP (adenosine triphosphate). It also produces carbon dioxide and water as waste products.
Based on the given options, the correct answer is:
1. ATP
Cellular respiration produces several products. The main product is ATP (adenosine triphosphate), which is the main source of energy for cellular processes. During cellular respiration, glucose and oxygen are used to produce carbon dioxide, water, and ATP. The chemical equation for cellular respiration is:
C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP
In addition to ATP, cellular respiration also produces heat as a byproduct.
Cellular respiration is the process by which cells obtain energy from organic molecules. The main products of cellular respiration are ATP (Adenosine Triphosphate), carbon dioxide (CO2), and water (H2O).
To understand how cellular respiration produces these products, we need to look at the different stages of the process. Cellular respiration can be divided into three main stages: glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation (also known as the electron transport chain).
During glycolysis, glucose (a sugar molecule) is broken down into two molecules of pyruvate. This process occurs in the cytoplasm of the cell and results in the net production of two molecules of ATP and two molecules of NADH (a coenzyme).
The pyruvate molecules produced during glycolysis then enter the mitochondria, where the citric acid cycle takes place. In this cycle, each pyruvate molecule is further broken down, releasing carbon dioxide and transferring high-energy electrons to carrier molecules such as NADH and FADH2. The main product of the citric acid cycle is more NADH and FADH2, as well as a small amount of ATP.
Finally, the NADH and FADH2 molecules generated during the previous stages enter the oxidative phosphorylation phase, which occurs in the inner membrane of the mitochondria. Here, the high-energy electrons are passed along a series of protein complexes, creating a flow of protons (H+) and generating a large amount of ATP through a process called chemiosmosis. The final products of this stage are ATP and water.
In summary, by going through the stages of glycolysis, the citric acid cycle, and oxidative phosphorylation, cellular respiration produces ATP, carbon dioxide, and water.
