Overview of Metabolism

36.2K
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...

Overview of Protein Metabolism

2.9K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Overview of Nitrogen Metabolism

10.4K
Nitrogen is a very important element for life because it is a major constituent of proteins and nucleic acids. It is a macronutrient, and in nature, it is recycled from organic compounds and stored in the form of  ammonia, ammonium ions, nitrate, nitrite, or  nitrogen gas by many metabolic processes. Many of these metabolic processes are carried out only by prokaryotes.
The largest pool of nitrogen available in the terrestrial ecosystem is gaseous nitrogen (N2) from the air, but this...

Key Elements for Plant Nutrition

23.3K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Introduction to Metabolism01:30

Introduction to Metabolism

1.6K
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...

Regulation of Metabolism01:19

Regulation of Metabolism

10.8K
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...

Summary

Plant-based diets, including veganism, are linked to potential health benefits like lower cholesterol and reduced cancer risk compared to omnivore diets. However, the exact reasons and widespread applicability of these health advantages remain unclear.

Area of Science:

  • Nutrition Science
  • Dietary Studies
  • Public Health

Background:

  • Plant-based diets are increasingly popular due to perceived sustainability and health advantages.
  • Veganism, a strict form of plant-based eating, excludes all animal products.
  • Observational studies suggest vegans and vegetarians may have lower body mass index, cholesterol, and reduced risks of heart disease and cancer.

Purpose of the Study:

  • To explore the health benefits associated with plant-based and vegan diets.
  • To investigate the potential mechanisms behind observed health outcomes in vegans and vegetarians.
  • To assess the generalizability of these health benefits across populations.

Main Methods:

  • Review of observational studies comparing plant-based/vegan diets with omnivore diets.
  • Analysis of reported health markers such as body mass index and cholesterol levels.
  • Examination of incidence and mortality rates for ischemic heart disease and cancer.

Main Results:

  • Studies indicate vegans and vegetarians tend to have lower body mass index and LDL-cholesterol.
  • Evidence suggests a decreased incidence and mortality from ischemic heart disease in plant-based eaters.
  • Reduced incidence of certain cancers has been observed in vegan and vegetarian populations.

Conclusions:

  • Plant-based diets, particularly veganism, show potential health benefits including improved cardiovascular markers and lower cancer risk.
  • The mechanistic underpinnings for these observed health improvements require further elucidation.
  • The broad applicability and long-term effects of these dietary patterns warrant additional investigation.
