What are two examples of processes that require oxygen?
Cellular Respiration : Example Question #6 Explanation: The Krebs cycle and the electron transport chain are both aerobic processes, meaning that they do require oxygen to require.
What process requires oxygen quizlet?
Metabolic process that requires oxygen. Metabolic processes that doesn't require oxygen.
What are three processes that require oxygen?
Glycolysis can take place without oxygen in a process called fermentation. The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur.
What type of respiration requires oxygen?
aerobic respiration If it requires oxygen it is called aerobic respiration, whereas if it takes place in the absence of oxygen it is anaerobic respiration.
Does photosynthesis require oxygen?
No, photosynthesis does not require oxygen, instead, oxygen is produced by photolysis of water and released in the atmosphere.
Does fermentation require oxygen?
Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis. One type of fermentation is alcohol fermentation. First, pyruvate is decarboxylated (CO2 leaves) to form acetaldehyde.
Does glycolysis require oxygen?
Glycolysis requires no oxygen. It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen. For these reasons, glycolysis is believed to be one of the first types of cell respiration and a very ancient process, billions of years old.
Does respiration use oxygen?
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.
Do you need oxygen to make alcohol?
Alcoholic fermentation, also referred to as ethanol fermentation, is a biological process by which sugar is converted into alcohol and carbon dioxide. Yeasts are responsible for this process, and oxygen is not necessary, which means that alcoholic fermentation is an anaerobic process.
Does Calvin cycle require oxygen?
The Calvin Cycle converts three water and three carbon dioxide molecules into one molecule of glyceraldehyde. The six left over oxygen atoms are released into the atmosphere where they are available for use in respiration.
What fermentation requires oxygen?
Aerobic fermentation occurs in the presence of oxygen. It usually occurs at the beginning of the fermentation process. Aerobic fermentation is usually a shorter and more intense process than anaerobic fermentation.
What is the process of photorespiration?
1.1. The Origin and Significance of Photorespiration. Photorespiration is the process of light-dependent uptake of molecular oxygen (O2) concomitant with release of carbon dioxide (CO2) from organic compounds. The gas exchange resembles respiration and is the reverse of photosynthesis where CO2 is fixed and O2 released …
Is oxygen required for glycolysis?
Glycolysis requires no oxygen. It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen. For these reasons, glycolysis is believed to be one of the first types of cell respiration and a very ancient process, billions of years old.
Does photorespiration need oxygen?
The reaction of RUBISCO with oxygen and metabolic processing of the resulting 2-PG is called "photorespiration". It is called this because it only occurs in the light (mitochondrial respiration continues in darkness) and because it consumes oxygen and produces carbon dioxide, just like mitochondrial respiration.
What is photorespiration process?
Photorespiration is the chemical processes that occur within a living organism of phosphoglycolate that is produced during oxygenation catalyzed by the enzyme RubisCO and inhibits photosynthesis by interfering with CO2 fixation by RubisCO.
What is the difference between photosynthesis and photorespiration?
The main difference between photosynthesis and photorespiration is that the photosynthesis occurs when RuBisCO enzyme reacts with carbon dioxide while the photorespiration occurs when RuBisCO enzyme reacts with oxygen. Furthermore, photorespiration reduces the efficiency of photosynthesis.
What is photorespiration short answer?
Photorespiration is the chemical processes that occur within a living organism of phosphoglycolate that is produced during oxygenation catalyzed by the enzyme RubisCO and inhibits photosynthesis by interfering with CO2 fixation by RubisCO.
What is plant respiration?
Respiration is a chain of chemical reactions that enables all living entities to synthesize energy required to sustain. It is a biochemical process wherein air moves between the external environment and the tissues and cells of the species.
What are the 4 types of respiration?
Key Takeaways: Types of Respiration External respiration is the breathing process. It involves inhalation and exhalation of gases. Internal respiration involves gas exchange between the blood and body cells. Cellular respiration involves the conversion of food to energy.
What is the process of photosynthesis and respiration?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
What is the 3 type respiration?
Respiration is the process of gas exchange between the air and an organism's cells. Three types of respiration include internal, external, and cellular respiration.
What are the 2 main types of respiration?
There are two types of Respiration:
- Aerobic Respiration — Takes place in the presence of oxygen.
- Anaerobic Respiration –Takes place in the absence of oxygen.
What type of cellular respiration requires oxygen?
aerobic respiration If it requires oxygen it is called aerobic respiration, whereas if it takes place in the absence of oxygen it is anaerobic respiration.
Does chemosynthesis require oxygen?
Aerobic chemosynthesis depends on oxygen, which ultimately originates from photosynthetic processes occurring in the photic zone. Anaerobic chemosynthesis depends on terminal electron acceptors other than oxygen (e.g., S0, SO42-, CO2, Fe3+, NO3-, etc.), and therefore it is independent from photosynthetic processes.
What are the 4 processes of respiration?
There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation. During glycolysis, glucose molecules (six-carbon molecules) are split into two pyruvates (three-carbon molecules) during a sequence of enzyme-controlled reactions. This occurs in both aerobic and anaerobic respiration.
Does photosynthesis produce oxygen?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What is the process of photosynthesis?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Which type of process is respiration?
catabolic process Respiration is a catabolic process. In respiration, glucose breakdown to form ATP (energy).
Does cellular respiration require oxygen?
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.
What are the three process of photosynthesis?
The three episodes that occur during the photosynthesis cycle are: Light energy is absorbed by chlorophyll, which breaks down water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. The reduction of carbon dioxide leads to the formation of carbohydrates.
