  • Post-absorptive state

    During a specific interval of time, the gastrointestinal tract is devoid of any contents, and the body’s energy requirements are met by the breakdown of its reserves, which consist of glycogen and triglycerides.  

  • Placental lactogen

    This particular polypeptide hormone bears a resemblance in both structure and function to the hormone responsible for human growth. Its significance lies in its facilitation of energy supply for the developing fetus.  

  • Phosphate loading

    Consuming phosphate and phosphorus prior to engaging in intense physical activity in order to improve the synthesis of adenosine triphosphate (ATP) and the transportation of oxygen to muscle cells.  

  • Pyruvate dehydrogenase

    The catalytic process that breaks down pyruvate into acetyl-CoA is facilitated by an enzyme.  

  • Phosphagen system

    The ATP-PCr system, otherwise known as the phosphagen system, is a mechanism that acts as a direct source of energy for the resynthesis of adenosine triphosphate (ATP).  

  • Propagative virus

    A pathogen that is recognized for replicating inside its carrier. These types of pathogens tend to be distributed throughout the organism, but it’s crucial to understand that these terms do not have the same meaning.  

  • Persistent virus

    This passage discusses viruses that are maintained over extended periods, sometimes even throughout the entire lifespan, through transmission from infected to healthy plants by vectors. These viruses exhibit distinct transmission traits, such as passing through the moult, and some can pass on to the vector’s offspring and even multiply within it. They are carried inside…

  • Primary symptom

    The initial indication to manifest in a malady that has the capacity to generate a variety of symptom types.  

  • Polygenic resistance

    Resistance to diseases or pests in plants is influenced by multiple genes, known as polygenes. These genes control a quantitative characteristic, meaning that the level of resistance is not determined by a single gene, but rather by the collective effect of many genes. It is important to note that this type of resistance is distinct…

  • Passive resistance

    Passive resistance refers to a form of resistance exhibited by the host in the presence of a pathogen that does not involve any defensive reactions. Such resistance can stem from the host’s physical or chemical attributes that impede the pathogen’s ability to infect or from a lack of qualities that aid in infection facilitation or…
