Metabolism of Chemolithotrophs01:15

Metabolism of Chemolithotrophs

1.1K
Chemolithotrophs are microorganisms that obtain energy by oxidizing inorganic molecules such as hydrogen gas (H₂), ammonia (NH₃), reduced sulfur compounds (H₂S, S²⁻), and ferrous iron (Fe²⁺). Unlike heterotrophic organisms that rely on organic carbon, chemolithotrophs transfer electrons from these inorganic donors to the electron transport chain (ETC), generating a proton motive force (PMF) that drives ATP synthesis through oxidative phosphorylation.

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...

Overview of Metabolism

40.6K
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...

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...

Area of Science:

  • Ecology
  • Metabolic Ecology
  • Theoretical Ecology

Background:

  • Metabolic theory of ecology (MTE) primarily focuses on organismal metabolic rates.
  • Generalizing metabolic ecology requires understanding energy flow through ecosystems.
  • A bibliometric analysis reveals key research clusters in metabolic ecology.

Discussion:

  • Metabolic ecology integrates MTE with foraging theory, bioenergetics, and trophic status.
  • The field encompasses scaling, temperature, and stoichiometric models.
  • It includes life-history allocation, consumer-resource dynamics, and macroecology models.

Key Insights:

  • Metabolic ecology offers a unified framework linking ecological outcomes to biophysical processes.
  • The research network shows distinct but interconnected clusters.
  • Standardized metabolic rates are insufficient; energy flow is crucial.

Outlook:

  • Advancing metabolic ecology requires further integration of diverse theoretical approaches.
  • A second fundamental equation is proposed to complement MTE.
  • Future research should focus on energy transfer and allocation across scales.
