They can work via allosteric inhibition, where the final product in large amounts binds to a site (not the active site, but an allosteric site) which stops the enzymes involved in the early phases of the metabolic pathway. In other words, the final product can act as an inhibitor to stop the enzyme early in the metabolic pathway by deactivating it.

How many metabolic pathways?
There are thousands of metabolic pathways in a cell. These pathways are interconnected processes that convert molecules into energy, synthesize new molecules, and perform various other functions essential for life. Each pathway is tightly regulated to ensure proper functioning of the 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.
WHAT ARE CHARACTERISTICS Metabolic pathways?
Metabolic pathways are series of interconnected biochemical reactions that occur within a cell to convert substrates into products, facilitating cellular function and energy production. They are typically categorized into anabolic pathways, which build complex molecules from simpler ones, and catabolic pathways, which break down molecules to release energy. These pathways are highly regulated and often involve enzymes that catalyze each reaction, ensuring efficiency and responsiveness to the cell's needs. Additionally, metabolic pathways can be interconnected, allowing for the integration of various metabolic processes.
Do metabolic reactions occur in isolation?
Metabolic reactions do not occur in isolation, as they are interconnected and form complex metabolic pathways within cells. These pathways involve a series of reactions that are tightly regulated and coordinated to maintain cellular function and energy balance. The products of one reaction often serve as substrates for the next, allowing for efficient energy production and utilization.
What is the purpose of metabolic pathways?
Metabolic pathways are a series of chemical reactions that help cells convert nutrients into energy, building blocks for growth, and molecules needed for various cellular processes. These pathways regulate metabolism and help maintain cellular functions and homeostasis.
How are metabolic pathways regulated to maintain cellular homeostasis?
Metabolic pathways are regulated through feedback mechanisms and enzyme activity to maintain cellular homeostasis. This ensures that the production and breakdown of molecules within the cell are balanced, allowing for proper functioning and stability.

How many metabolic pathways are there?
There are hundreds of metabolic pathways in living organisms, as they encompass various biochemical processes necessary for life. These pathways can be broadly categorized into two main types: catabolic pathways, which break down molecules to produce energy, and anabolic pathways, which use energy to synthesize complex molecules. Some well-known metabolic pathways include glycolysis, the Krebs cycle, and oxidative phosphorylation. The exact number of pathways can vary depending on the organism and the specific metabolic processes considered.
What are the anaplereotic sequences and amphibolic pathways?
Anaplerotic sequences are metabolic pathways that replenish intermediates in central metabolic cycles, such as the tricarboxylic acid cycle, to maintain metabolic flux. Amphibolic pathways are metabolic pathways that serve both catabolic and anabolic roles, allowing bidirectional flow of metabolites for energy generation and biosynthesis. Together, anaplerotic sequences and amphibolic pathways help regulate metabolism and maintain cellular homeostasis.
What is the general term for all types of coordinated sequences of chemical pathways?
metabolic pathways
Why do metabolic pathways require tens to hundreds of different enzymes?
Metabolic pathways require multiple enzymes to carry out specific chemical reactions at each step. Each enzyme catalyzes a specific reaction within the pathway, helping to regulate the overall flow of molecules and energy. This ensures that metabolic processes are efficient and tightly controlled.
Without enzymes the metabolic pathways are?
Without enzymes, metabolic pathways would be extremely slow or unable to proceed because enzymes are needed to catalyze the chemical reactions that occur in these pathways. Enzymes lower the activation energy required for these reactions to take place, allowing them to occur efficiently within cells.
What is metabolic activity in a cell?
Metabolic activity is the constant flow of molecules through metabolic pathways that maintains an organism's life.
