What happens during aerobic respiration quizlet?
Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules. You just studied 9 terms!
What is aerobic respiration short answer?
Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. Most eukaryotes and prokaryotes use aerobic respiration to obtain energy from glucose.
What does aerobic cellular respiration occur in?
While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.
What are the three steps that occur in aerobic respiration?
Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain.
What two stages of respiration are aerobic quizlet?
The Stages of Aerobic Respiration
- Glycolysis.
- The Krebs Cycle.
- The Electron Transport System.
How does anaerobic respiration occur?
Anaerobic respiration in humans occurs in muscles during strenuous exercise when sufficient oxygen is not available. … Less energy is produced in anaerobic respiration due to the partial breakdown of glucose. Pyruvic acid, which is the product of glycolysis is converted into lactic acid by lactate dehydrogenase.
What is aerobic and anaerobic process?
While both rely on a process of microbial decomposition to treat wastewater, the key difference between anaerobic and aerobic treatment is that aerobic systems require oxygen, while anaerobic systems do not. This is a function of the types of microbes used in each type of system.
What is common in aerobic and anaerobic respiration?
The similarities between aerobic and anaerobic respiration, is that they both use glucose as the starting molecule. This is called the substrate. In addition, both aerobic and anaerobic respiration produce ATP, however, aerobic respiration produces a lot more ATP compared to anaerobic respiration.
What happens during anaerobic cellular respiration?
Answer: During anaerobic cellular respiration, glucose is broken down without oxygen. The chemical reaction transfers glucose energy to the cell. In fermentation, instead of carbon dioxide and water, lactic acid is produced which can lead to painful muscle cramps.
Which is formed during anaerobic respiration *?
Explanation: In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water.
Which of the following is formed during anaerobic respiration?
The correct answer is Ethanol + carbon dioxide + energy. Yeast breaks down glucose, forming ethanol and carbon dioxide and energy.
What happens during anaerobic respiration quizlet?
What happens during anaerobic respiration? Glucose is not broken down completely, produces lactic acid,releases small amount of energy for cells ( not as efficient as aerobic respiration,as glucose molecules aren’t broken down completely. You just studied 7 terms!
What are the two stages of anaerobic respiration?
In the glycolysis, the glucose molecule breaks down into two three carbon compound pyruvic acid. In the second stage, the pyruvic acid undergoes incomplte oxidation i.e., fermentation. The incompplete oxidation of the pyruvic acid yields ethano or lactic acid.
What are the products formed during aerobic and anaerobic respiration?
Aerobic respiration vs anaerobic respiration
| Aerobic | Anaerobic | |
|---|---|---|
| Oxygen | Needed | Not needed |
| Glucose breakdown | Complete | Incomplete |
| End product(s) | Carbon dioxide and water | Animal cells: lactic acid. Plant cells and yeast: carbon dioxide and ethanol |
| Energy released | Relatively large amount | Relatively small amount |
What are being formed during anaerobic respiration in muscles?
Anaerobic respiration in muscles
The creation of lactic acid (which needs oxygen to be broken down) generates an oxygen debt that needs to be repaid after the exercise stops.
Which of the following is not released during aerobic respiration?
During anaerobic respiration (absence of oxygen), the unicellular fungus (yeast) breaks down the glucose into ethanol (C2H5OH) and carbon dioxide (CO2) and releases energy in the form of ATP. Hence water molecule (H2O) is not released.
What are the end products formed in aerobic respiration?
Carbon dioxide, water and energy.
What is the end product of the aerobic respiration?
Anaerobic respiration
| Aerobic respiration | |
|---|---|
| Oxidation of glucose | Complete |
| Reactants of respiration | Glucose and oxygen |
| Products of respiration | Carbon dioxide and water (and ATP) |
| Amount of ATP made | Large amount |
Which of the following is absent during anaerobic respiration?
Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration.
Which of the following is not an aerobic reaction?
Explanation: aerobic respiration takes place in 3 steps namely glycolysis, kerb cycle, Electron transfer chain reaction. anaerobic respiration occurs in 2 steps namely glycolysis and fermentation.
Which of the following is not involved in anaerobic respiration?
