Catabolic and anabolic pathways are often coupled in the cell because?
Catabolic pathways break down molecules to release energy, while anabolic pathways use that energy to build molecules. By coupling these pathways, cells can efficiently regulate energy balance and maintain homeostasis. This ensures that energy released from catabolic reactions is used effectively for building new molecules in anabolic reactions.
Which statemenst are true concerning anabolic pathways?
Anabolic pathways are energy-consuming processes that build complex molecules from simpler ones. They are responsible for growth, repair, and maintenance of cells and tissues. Anabolic pathways are important for storing energy in the form of chemical bonds.
What is the difference between catabolic and anabolic pathways in terms of their roles in cellular metabolism?
Catabolic pathways break down molecules to release energy, while anabolic pathways build molecules using energy. Catabolic pathways are involved in breaking down nutrients for energy production, while anabolic pathways are responsible for synthesizing complex molecules needed for growth and repair in cells.
What term is used to describe the transfer of free energy from cataboloic pathways to anabolic pathways?
The term used to describe the transfer of free energy from catabolic pathways to anabolic pathways is "energy coupling." This process allows cells to use the energy generated from breaking down molecules in catabolic reactions to drive the energy-requiring anabolic reactions for growth and maintenance.
What metabolic pathway is anabolic?
anabolic pathway is one that the products are more complicated than reactants. they usually need energy(ΔG>0) anabolic pathways are enzymatic and occur in living organism cells and uses energy to construct components of cells such as protein and nucleic acid.
How are synthesis and decomposition reactions coupled in cells?
In cells, synthesis and decomposition reactions are coupled through metabolic pathways. Synthesis reactions build complex molecules by combining simpler ones, while decomposition reactions break down complex molecules into simpler components. These reactions are interconnected in metabolic pathways, where the products of one reaction serve as substrates for another, allowing cells to efficiently produce and break down molecules as needed.
What are two pathways that might follow glycolysis?
Two pathways that might follow glycolysis are aerobic respiration and fermentation. In aerobic respiration, pyruvate is further broken down in the presence of oxygen to produce more ATP. In fermentation, pyruvate is converted into different byproducts (such as lactic acid or ethanol) in the absence of oxygen, generating a small amount of ATP.
Do anabolic pathways depend on enzymes?
Yes, anabolic pathways depend on enzymes to catalyze the synthesis of complex molecules from simpler ones. Enzymes are biological catalysts that lower the activation energy required for these synthetic reactions to occur efficiently in cells.

How do G-protein coupled receptors work to transmit signals within cells?
G-protein coupled receptors (GPCRs) work by binding to specific molecules outside the cell, which triggers a series of events inside the cell. When a molecule binds to the GPCR, it activates a G-protein inside the cell, which then triggers a cascade of signaling pathways that ultimately lead to a cellular response. This allows cells to respond to external signals and regulate various processes within the body.
What do peoxisomes do?
If you mean peroxisomes, in animal cells they carry the enzymes needed for biosynthetic pathways, metabolic pathways, and detoxification. In some plant cells they are called glyoxysomes and carry enzymes for glyoxylate cycle.
Are cells with interconnected cytoplasm chemically coupled?
Yes, cells with interconnected cytoplasm can be chemically coupled due to gap junctions. Gap junctions allow for direct communication and exchange of small molecules between neighboring cells, enabling coordinated responses and signaling among the interconnected cells.
