What are 3 metabolic pathways in plants associated with the metabolism of carbohydrates?
Three key metabolic pathways in plants associated with carbohydrate metabolism are glycolysis, the Calvin cycle, and the pentose phosphate pathway. Glycolysis breaks down glucose to produce energy in the form of ATP and pyruvate. The Calvin cycle, occurring in the chloroplasts, converts carbon dioxide and ribulose bisphosphate into glucose during photosynthesis. The pentose phosphate pathway generates NADPH and ribose-5-phosphate, which are essential for biosynthetic reactions and nucleotide synthesis.

What is the result of mitochondria?
When biochemical pathways, primarily from metabolism of carbohydrates and lipids, converge to oxidative phosphorylation, the major process in mitochondria, the major product is ATP needed to multiple metabolic processes.
Energy is derived mainly from the metabolism of?
carbohydrates, fats, and proteins. These nutrients are broken down in the body through various metabolic pathways to produce energy in the form of adenosine triphosphate (ATP), which fuels cellular processes. Oxidative phosphorylation in the mitochondria is the main process by which energy is generated from the metabolism of these nutrients.
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.
Are metabolic pathways the same as biochemical pathways?
Yes, metabolic pathways and biochemical pathways are often used interchangeably to describe the sequences of biochemical reactions within a cell that lead to the synthesis or breakdown of molecules. They encompass a series of interconnected chemical reactions that ultimately govern cellular metabolism.
What stage of cellular respiration do fats proteins and carbohydrates enter the metabolic pathway?
Fats, proteins, and carbohydrates enter the metabolic pathway of cellular respiration during the acetyl-CoA formation stage. Fats and carbohydrates are broken down into acetyl-CoA through different pathways, while proteins are converted into amino acids, which can then enter the acetyl-CoA formation stage.
Where does cell metabolism occur?
Cell metabolism occurs primarily in the cytoplasm of the cell, where various metabolic processes such as glycolysis, protein synthesis, and lipid metabolism take place. Additionally, organelles such as mitochondria and chloroplasts are involved in specific metabolic pathways within 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.
How does arsenic effect Metabolism?
Arsenic can disrupt metabolism by inhibiting enzymes involved in processes such as glucose metabolism and energy production. It can interfere with the function of key metabolic pathways, leading to metabolic imbalances and dysfunction in various organs and tissues. Chronic exposure to arsenic has been linked to metabolic disorders such as diabetes and cardiovascular disease.
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.
Show the relationship of metabolic pathways for all nutrient metabolism along with major organs and cells of primary permanent sites of activity?
Nutrient metabolism involves various pathways that occur in different organs and cells. For example, carbohydrate metabolism primarily occurs in the liver, muscle, and adipose tissue, while lipid metabolism happens mainly in adipose tissue and the liver. Protein metabolism takes place in the liver and various tissues throughout the body. These pathways are interconnected, with organs like the liver playing a central role in coordinating the metabolism of different nutrients.
Do plants absorb carbon dioxide?
Plants use CO2 in photosynthesis. They convert CO2 and H2O into carbohydrates through a series of metabolic pathways.
