Regulation of Metabolism01:19

Regulation of Metabolism

12.0K
Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

Metabolic States of the Body: The Postabsorptive State

1.5K
The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

Introduction to Metabolism

3.3K
Metabolism encompasses all biochemical reactions in a living organism, facilitating both the breakdown and synthesis of biomolecules. These metabolic processes are categorized into catabolic and anabolic pathways, which operate in a coordinated manner to ensure energy balance and cellular function.Catabolic Pathways and Energy ReleaseCatabolic pathways involve the breakdown of complex macromolecules such as carbohydrates, lipids, and proteins into smaller structures like monosaccharides, fatty...

Metabolic Rate

1.3K
The human body is a powerhouse of energy, with every cell performing numerous functions that require energy. This energy production and consumption is measured by the metabolic rate, which quantifies the total heat generated by all the body's chemical reactions and mechanical work. This measurement helps to determine the rate of kilocalorie (kcal) consumption needed to fuel all ongoing activities.
The Basal Metabolic Rate (BMR) measures the energy expended at rest.
Several factors influence...

Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Area of Science:

  • Biochemistry
  • Metabolic Medicine
  • Trauma Surgery

Background:

  • Severe burns precipitate a persistent hypermetabolic state, elevating metabolic demands and leading to detrimental catabolism of muscle, bone, and adipose tissue.
  • This metabolic derangement increases the risk of severe complications, including multi-organ dysfunction, sepsis, and mortality, despite advancements in burn care.
  • The complex, multifactorial nature of post-burn hypermetabolism hinders precise identification and pharmacological modulation of contributing biological mediators.

Purpose of the Study:

  • To review key biomarkers and molecules involved in the induction and mediation of hypercatabolism following thermal injury.
  • To elucidate the development of factors released post-burn and their mechanisms in causing cellular and metabolic dysfunction.
  • To identify potential therapeutic targets for interventions aimed at restoring a physiological metabolic state after severe burns.

Main Methods:

  • Comprehensive literature review of existing research on post-burn hypermetabolism.
  • Analysis of identified biomarkers and molecular mediators.
  • Discussion of therapeutic strategies targeting identified factors.

Main Results:

  • Identified critical biomarkers and molecules implicated in the hypermetabolic and hypercatabolic response to severe burns.
  • Detailed the cascade of events from burn injury to cellular dysfunction, driven by released factors.
  • Highlighted potential therapeutic avenues for modulating these factors to mitigate metabolic derangement.

Conclusions:

  • Understanding the molecular mediators of burn-induced hypermetabolism is crucial for developing effective treatments.
  • Targeting specific biomarkers and molecular pathways offers a promising strategy to restore metabolic homeostasis after severe thermal injuries.
  • Further research into these factors could lead to novel pharmacological interventions to improve patient outcomes.
