Cellular respiration is the process in which cells break down glucose, release the stored energy, and use it to make ATP. The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.29-Feb-2012
What time does cellular respiration occur?
Respiration is essential for all living organisms and this includes plants. If respiration stops in a plant it will die, so plants constantly respire during the day and through the night. Respiration is a different process to photosynthesis, which depends on sunlight and therefore takes place only during the day.
Does cellular respiration occur all the time?
Plants respire all the time, day and night. But photosynthesis only occurs during the day when there is sunlight.
Under what conditions does cellular respiration occur?
Cellular respiration can occur both aerobically (using oxygen ), or anaerobically (without oxygen ). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.
Where and when does cellular respiration take place?
Cellular respiration is the process whereby energy is harvested from carbon compounds (food molecules) as they pass through a series of enzyme catalyzed reactions. The enzymatic reactions of cellular respiration begin in the cytoplasm, but most of the reactions occur in the mitochondria.
What are the 3 main parts of cellular respiration?
Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain.
Does cellular respiration occur at night?
Cellular Respiration in plants occur both during the day and in the night, but the rate of respiration will be high during the night.
What two stages does cellular respiration occur?
Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Glycolysis is an anaerobic process. The other two stages are aerobic processes. The products of cellular respiration are needed for photosynthesis, and vice versa.
What is the basic purpose of cellular respiration?
Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
Does cellular respiration occur in bacteria?
Cellular respiration is an energy generating process that occurs in the plasma membrane of bacteria. Glucose is broken down into carbon dioxide and water using oxygen in aerobic cellular respiration, and other molecules such as nitrate (NO3) in anaerobic cellular respiration, meaning simply, without oxygen.
Can you identify the stages of cellular respiration?
The reactions of cellular respiration can be grouped into three stages: glycolysis, the Krebs cycle (also called the citric acid cycle), and electron transport.
What is the cellular respiration formula?
C 6 H 12 O 6 + 6 O 2 –> 6 CO 2 + 6 H 2 O + ATP is the complete balanced chemical formula for cellular respiration.
What are the 3 stages of anaerobic respiration?
Making ATP Without Oxygen This process occurs in three stages: glycolysis, the Krebs cycle, and electron transport. The latter two stages require oxygen, making cellular respiration anaerobic process.
What is the difference between the use of the terms cellular respiration and respiration in biology?
What is the difference between the use of the terms cellular respiration and respiration in biology? Cellular respiration refers only to the breakdown of energy-rich molecules to produce ATP; respiration can refer to breathing. In human muscle cells lactic acid is produced, while yeast produces ethyl alcohol.
Where does bacterial respiration occur?
Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells. More emphasis here will be placed on eukaryotic cells where the mitochondria are the site of most of the reactions.
