Food-chain.
The glycolysis pathway is found in almost all organisms. It is a fundamental metabolic pathway that involves the breakdown of glucose to produce energy in the form of ATP.
In a direct pathway for bioaccumulation, organisms take in contaminants directly from the environment through processes like ingestion or absorption. In an indirect pathway, organisms accumulate contaminants by consuming other organisms that have already bioaccumulated the contaminants.
A food web shows the complex network of feeding relationships in an ecosystem, including multiple interconnected food chains. This provides a more comprehensive and realistic understanding of how energy and nutrients flow through an ecosystem, compared to a food chain which only shows a single linear pathway of energy transfer.
The glyoxylate pathway occurs in the peroxisomes of eukaryotic cells and in the cytoplasm of prokaryotic cells. It is a metabolic pathway that allows some organisms to convert fatty acids into carbohydrates for energy production.
The alternative pathway in the immune response is activated when certain molecules on the surface of pathogens, called microbial patterns, are recognized by proteins in the blood. This recognition triggers a cascade of reactions that lead to the activation of the alternative pathway, which helps to eliminate the pathogen.
Electron transport chain and oxidative phosphorylation
The old pathway in the brain refers to well-established neural connections and habits, while the new pathway refers to forming new connections through learning and adaptation. The old pathway is efficient but can lead to automatic responses, while the new pathway allows for flexibility and personal growth. Stimulating the new pathway can help break free from old patterns and create new ways of thinking and behaving.
Various enzymes catalyze each step of a metabolic pathway. Enzymes are biological catalysts that speed up chemical reactions in living organisms. Each step of a pathway requires a specific enzyme to facilitate the conversion of substrates into products.
All organisms perform cellular respiration, which involves the breakdown of glucose to release energy in the form of ATP. This process occurs in the mitochondria of cells and is essential for the survival of all living organisms.
