During recovery, when oxygen becomes available, NAD+ attaches to hydrogen from lactate to form ATP. In yeast, the waste products are ethanol and carbon dioxide. This type of fermentation is known as alcoholic or ethanol fermentation. The ATP generated in this process is made by substrate-level phosphorylation, which does not require oxygen.
What else can I help you with?
What are the 2 metabolic pathways a cell can use and what determines which pathway is being used?
Cells can use aerobic (oxidative) and anaerobic (glycolytic) pathways. The availability of oxygen determines which pathway is being used; aerobic pathways are utilized in the presence of oxygen, while anaerobic pathways are used when oxygen is limited. Oxygen is essential for the electron transport chain in aerobic metabolism, while glycolysis can proceed in the absence of oxygen.
What is a catabolic pathway in which organic molecules are broken down to release energy for use by the cell?
Glycolysis is a catabolic pathway in which glucose is broken down in the cytoplasm of the cell to produce ATP and NADH. This process is the first step in cellular respiration and helps generate energy for the cell to use in various metabolic processes.
What factor can determine which of those pathways a cell might follow?
The factors that can determine which pathway a cell might follow include external signals from the cell's environment, internal genetic and epigenetic regulation, and cell-to-cell communication. These factors can influence a cell's decision to divide, differentiate, or undergo programmed cell death.
What cells major basic needs?
All cells require nutrients such as carbohydrates, proteins, and fats for energy production and to maintain cellular functions. Additionally, cells need oxygen for cellular respiration to generate ATP, the cell's energy currency, and to carry out essential metabolic reactions. Cells also require water to maintain cell structure and support various biochemical processes.
Where does beta-oxidation occur in the cell?
Beta-oxidation occurs in the mitochondria of a cell. It is a metabolic pathway that breaks down fatty acids to generate acetyl-CoA, which can then enter the citric acid cycle to produce energy.
A cell obtains energy during the process of?
Cells obtain energy through different processes depending on whether they are aerobes (those that require oxygen to survive) or anaerobes (those that do not require oxygen).However, the metabolic pathway that results in the production of energy is a majority of aerobes is called Oxydative Phosphorylation
The first metabolic pathway ATP is made in an active muscle cell is?
Glycolysis
Which pathway dismantles carbons and is commonly called the bacterial cell's metabolic clearinghouse?
glycolysis
What are the 2 metabolic pathways a cell can use and what determines which pathway is being used?
Cells can use aerobic (oxidative) and anaerobic (glycolytic) pathways. The availability of oxygen determines which pathway is being used; aerobic pathways are utilized in the presence of oxygen, while anaerobic pathways are used when oxygen is limited. Oxygen is essential for the electron transport chain in aerobic metabolism, while glycolysis can proceed in the absence of oxygen.
What term describes a series of linked reactions in the cell directed towards producing some specific end produc?
A metabolic pathway describes a series of linked reactions in a cell that work together to produce a specific end product. Each step in the pathway is catalyzed by a specific enzyme, and the end product is essential for cellular function.
What is the catalyst in a metabolic pathway?
A catalyst in a metabolic pathway is typically an enzyme that speeds up the rate of a specific chemical reaction without being consumed in the process. Enzymes achieve this by lowering the activation energy required for the reaction to occur, allowing metabolic processes to proceed efficiently within the cell.
What factor can determine which pathway a cell might follow aerobic or anaerobic in glycolysis?
Oxygen
When oxygen delivery to the cell is impaired which pathway is used for energy production?
anaerobic respiration
What is a pathway in which the products of one reacction is fed into another reaction?
The pathway in which the products of one reaction is fed into another reaction could be Metabolic Pathways. These are a series of reactions that happen inside of a cell.
Complex metabolic reactions proceed in a series of steps called?
Complex metabolic reactions proceed in a series of steps called metabolic pathways. These pathways involve a sequence of enzymatic reactions that transform substrates into products, ultimately contributing to the overall metabolism of an organism. Each step in a metabolic pathway is tightly regulated and often linked to other pathways within the cell.
Is CO2 used in glycolysis?
No, CO2 is not directly involved in glycolysis. Glycolysis is the metabolic pathway that converts glucose into pyruvate, which can then be used in other pathways for energy production. Although CO2 does play a role in other metabolic processes in the cell, it is not a part of the glycolysis pathway.
Chains of enzyme reactions in a Cell that regulate enzyme activity and energy flow are known as?
Metabolic pathways. These pathways involve a series of enzyme-catalyzed reactions that help regulate the flow of energy and molecules within a cell. Each step in a metabolic pathway is carefully controlled to ensure proper functioning and homeostasis in the cell.
