What are advantages and disadvantages of cellular respiration?
It produces a lot more energy than simple fermentation. On the down side it requires oxygen which isn't always there. There is a complete breakdown of glucose during this process.
What does glucose react with in respiration?
Glucose reacts with oxygen in the process of cellular respiration to produce energy in the form of ATP (adenosine triphosphate) along with carbon dioxide and water as byproducts. This series of reactions occurs in multiple steps, with the final stages taking place in the mitochondria of the cell.
What role does the oxygen in cellular respiration play?
Oxygen serves as the final electron acceptor in the electron transport chain during cellular respiration, allowing for the production of ATP through oxidative phosphorylation. It helps in breaking down glucose molecules to release energy in the form of ATP through a series of metabolic reactions. Oxygen is essential for the efficient production of ATP in aerobic respiration.
Where does PGAL appear in cellular respiration?
PGAL (phosphoglyceraldehyde) appears in the Calvin cycle of photosynthesis, where it is produced from the reduction of 3-phosphoglycerate. It is not directly involved in cellular respiration, but its further conversion to glucose and other carbohydrates in plants provides the energy source for respiration in both plants and animals.
Glycolysis is the process that is not part of cellular respiration pathway that produces large amounts of ATP in a cell. While glycolysis produces some ATP, the majority of ATP production occurs in the citric acid cycle and oxidative phosphorylation.
Why are the byproducts of cellular respiration?
The byproducts of cellular respiration are carbon dioxide and water. These byproducts are produced as a result of the breakdown of glucose in the presence of oxygen to generate energy in the form of ATP.
What are the processes involved in aerobic cellular respiration?
Aerobic cellular respiration involves four main processes: glycolysis, the citric acid cycle (Krebs cycle), oxidative phosphorylation, and the electron transport chain. During glycolysis, glucose is broken down into pyruvate. The citric acid cycle further breaks down pyruvate to generate ATP and NADH. Oxidative phosphorylation and the electron transport chain use NADH and FADH2 to produce ATP, the cell's main energy source.
What is the end productbof photosynthesis and cellular respiration?
The end product of photosynthesis is glucose and oxygen. The end products of cellular respiration are ATP (energy), carbon dioxide, and water.
Are the products of photosynthesis the raw materials of cellular respiration?
Yes, the products of photosynthesis, such as glucose and oxygen, are the raw materials needed for cellular respiration to occur. In cellular respiration, glucose is broken down in the presence of oxygen to produce energy in the form of ATP, which is used by cells for various functions.
What does the cellular respiration have to do with homeostasis?
Cellular respiration is crucial for homeostasis as it provides the energy needed for cells to maintain metabolic functions, such as maintaining body temperature, pH balance, and fluid levels. Without cellular respiration, cells would not have the energy required to perform essential functions necessary for maintaining homeostasis in the body.
What substances does the body need to carry out cellular respiration?
The body needs glucose and oxygen to carry out cellular respiration. Glucose is the primary source of energy, and oxygen is needed as the final electron acceptor in the electron transport chain to produce ATP.
What is the main organelle used in cellular respiration?
The main organelle used in cellular respiration is the mitochondrion. Mitochondria are known as the powerhouse of the cell because they generate ATP, the energy currency of the cell, through the process of cellular respiration.
Can cellular respiration happen without photosynthesis?
Yes, cellular respiration can occur without photosynthesis. Cellular respiration is the process by which cells generate energy from food molecules, while photosynthesis is the process by which plants convert sunlight into energy. Organisms like animals rely on cellular respiration to produce energy without needing photosynthesis.
How is cellular respiration different from anaerobic?
Cellular respiration is the process by which cells break down glucose with the use of oxygen to produce energy in the form of ATP. Anaerobic respiration, on the other hand, does not require oxygen and produces energy through the breakdown of glucose without the use of oxygen, resulting in the production of lactic acid or ethanol as byproducts.
What are the reactants products and basic functions of aerobic and anaerobic cellular respiration?
In aerobic cellular respiration, the reactants are glucose and oxygen, which are converted into carbon dioxide, water, and ATP molecules. This process occurs in the presence of oxygen and is the most efficient way for cells to produce energy. In anaerobic cellular respiration, the reactants are glucose alone, and the products can include lactic acid, ethanol, and ATP. This process occurs in the absence of oxygen and is less efficient in terms of ATP production compared to aerobic respiration.
How is C6H12O6 important to photosynthesis and cellular respiration?
C6H12O6 (glucose) serves as a key energy source in both photosynthesis and cellular respiration. In photosynthesis, plants synthesize glucose using CO2, water, and sunlight energy. During cellular respiration, glucose is broken down in the presence of oxygen to produce ATP, the energy currency of the cell.
Could cellular respiration work without photosynthesis?
Cellular respiration can occur without photosynthesis because it is the process by which cells convert glucose and oxygen into energy, water, and carbon dioxide. However, in nature, organisms rely on photosynthesis to provide the glucose and oxygen needed for cellular respiration.
Why is phosphorus important in cellular respiration?
Phosphorus is important in cellular respiration because it is a key component of ATP (adenosine triphosphate), which is the primary energy currency in cells. During cellular respiration, ATP is produced through processes like glycolysis, the citric acid cycle, and oxidative phosphorylation, where phosphorus is essential for the synthesis and transfer of energy within the cell.
What is a product if cellular respiration and not fermentation?
The end products of cellular respiration are carbon dioxide, water, and ATP (adenosine triphosphate). These products are generated through the breakdown of glucose and other organic molecules in the presence of oxygen in the mitochondria of the cell. Fermentation, on the other hand, produces end products such as alcohol or lactic acid in the absence of oxygen.
How are the photosynthesis and cellular respiration equations related?
The photosynthesis and cellular respiration equations are related through the carbon cycle. In photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen. In cellular respiration, organisms break down glucose using oxygen to produce carbon dioxide, water, and ATP. Thus, the products of one process (photosynthesis) are the reactants of the other (cellular respiration), creating a cycle where carbon atoms are continuously exchanged between living organisms and the atmosphere.
