What else can I help you with?
Why gluconeogenesis cannot be considered a reversal of glycolysis even though both pathways share reversible reactions?
In glycolysis you get pyruvate (or lactate) as a end product but in gluconeogenesis you get glucose formed from either Fat or Proteins. There are many intermediate steps before pyruvate is formed from Proteins and Fats. So gluconeogenesis cannot be considered as reversal of glycolysis.
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.
Which of the following statements about feedback regulation of metabolic pathways is correct?
Feedback regulation of metabolic pathways involves the inhibition of an enzyme by the end product of the pathway. This helps maintain homeostasis by preventing the overproduction of metabolites. This process is important for ensuring that a cell or organism does not waste resources on unnecessary synthesis.
All of the following are career pathways for Finance except?
Operations Management.
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.
Which of the following respiration pathways is this bacteria most likely to use?
anaerobic respiration
All of the biochemical pathways in a cell constitute?
Metabolism, which includes all the chemical reactions that occur within a cell. These pathways allow cells to carry out essential functions such as energy production, biosynthesis of molecules, and elimination of waste products. Overall, the interconnected biochemical pathways in a cell help maintain cellular homeostasis and support life processes.
How are the pathways of glycloysis and gluconeogenesis two sides of the same coin?
Glyoclysis (sugar break down) is a catabolic pathway of glucose where it is destined to provide energy or converted to other substance like glycogen or lipids. Gluconeogenesis on the other hand, is an anabolic process where glucose is produced from its non carbohydrate sources such as glucogenic amino acids, pyruvate,lactate,glycerol. The basis for both is "Glucose" (degradation or synthesis)
Which of the following does NOT describe the spinal cord tracts pathways?
memory. it does have relay, somatotype and decussation
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.
