What is the main function of cellular respiration?
Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level.
Does cellular respiration produce or require energy?
Cellular respiration is the process by which cells release energy from glucose and change it into a usable form called ATP. ATP is a molecule that provides a small amount of energy to the cell, which provides it fuel to do specific tasks. There are two types of respiration: anaerobic and aerobic. Anaerobic respiration does not use oxygen.
What is the overall reaction for cellular respiration?
The Net Chemical Reaction. The overall chemical reaction of cellular respiration converts one six-carbon molecule of glucose and six molecules of oxygen into six molecules of carbon dioxide and six molecules of water.
Is energy needed in cellular respiration?
Cellular respiration is the process we go through to provide ourselves with energy. The two basic requirements for cellular respiration is glucose and oxygen. GLUCOSE: We acquire glucose (C 6 H 12 O 6) from the food we eat.
What does cellular respiration start with?
Glycolysis is the first pathway that the cellular respiration process begins with. It is anaerobic (does not require oxygen) and occurs in the cytosol of our cells. Glycolysis is responsible for the conversion of one molecule of glucose (sugar) into two molecules of pyruvate.
What are the four phases of cellular respiration?
The four different phases of the cellular respiration process are: glycolysis, pyruvate oxidation, the citric acid cycle or Krebs cycle, and oxidative phosphorylation. Phases of cellular respiration detailed: Glycolysis , citric acid/Krebs cycle, electron transport chain.
What is the balanced equation for cellular respiration?
The balanced chemical equation for cellular respiration is C6H12 O6+ O2–> CO2 + H20 + ATP The process of cellular respiration releases byproducts, much as the process of photosynthesis does. In words, the equation may be stated as: Six carbon dioxide molecules and six water molecules react to produce one glucose molecule and six oxygen molecules.
