CELL RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Many different chemical reactions occur during cellular respiration. It is a process that requires certain resources to get started and in turn it produces resources when it is finished. With all of that being said, why do organisms want to perform cellular respiration? What is the main purpose?
A
To make H2O from CO2
B
To harvest energy from food
C
To create much needed O2
D
To create glucose
Explanation: 

Detailed explanation-1: -In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts. The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation.

Detailed explanation-2: -Cellular respiration location In eukaryotes, the 4 stages of cellular respiration include glycolysis, transition reaction (pyruvate oxidation), the Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation through the electron transport chain.

Detailed explanation-3: -These chemical reactions involving the transfer of electrons are called reduction-oxidation reactions, or redox reactions.

Detailed explanation-4: -The reactions of cellular respiration can be grouped into three main stages and an intermediate stage: glycolysis, Transformation of pyruvate, the Krebs cycle (also called the citric acid cycle), and Oxidative Phosphorylation. Figure 5.9.
