Compensation Mechanisms01:28

Compensation Mechanisms

205
The human body employs intricate mechanisms to counteract changes in blood pH, preventing conditions like acidosis (pH < 7.35) and alkalosis (pH > 7.45). These compensatory responses aim to restore normal arterial blood pH by engaging respiratory or renal systems, depending on the source of the imbalance.
Respiratory Compensation
This mechanism addresses metabolic-induced pH imbalances by adjusting breathing rates. Respiratory compensation begins within minutes of detecting a pH...

The Carbon Cycle01:14

The Carbon Cycle

37.1K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Carbon Dioxide Transport in the Blood01:19

Carbon Dioxide Transport in the Blood

1.7K
Carbon dioxide (CO2) transport in the blood is critical to human physiology. On average, our body cells produce around 200 mL of CO2 per minute, precisely the quantity expelled by the lungs. This process involves the transportation of CO2 from the tissue cells to the lungs in three primary forms.
Forms of CO2 Transport
1. Dissolved in plasma: A small percentage (7-10%) of CO2 is transported and dissolved directly in the plasma.
2. Carbaminohemoglobin: Just over 20% of CO2 is chemically bound to...

Short-distance Transport of Resources02:12

Short-distance Transport of Resources

15.6K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

1
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Respiratory Regulation of Acid-Base Balance01:18

Respiratory Regulation of Acid-Base Balance

312
Respiratory compensation is a vital physiological process that stabilizes blood plasma pH by regulating the partial pressure of carbon dioxide (PCO2), a key determinant of pH levels. Most carbon dioxide in the blood dissolves and converts into carbonic acid (H2CO3). It dissociates into hydrogen ions (H+) and bicarbonate ions (HCO3⁻). There is also an inverse relationship between PCO2​​ and pH.
When carbon dioxide levels increase in the blood, more H+ and HCO3⁻ are...

Area of Science:

  • Environmental Economics
  • Climate Change Policy
  • Industrial Ecology

Background:

  • Intercity trade in China causes significant embodied carbon transfers, leading to carbon leakage and complex emission responsibility accounting.
  • Traditional methods like Production-Based Accounting (PBA) and Consumption-Based Accounting (CBA) create imbalances, disadvantaging certain cities.
  • A fairer approach is needed to allocate emission responsibilities equitably among cities involved in trade.

Purpose of the Study:

  • To propose and evaluate a novel Value-Added Captured Responsibility Allocation (VCRA) scheme for intercity emission responsibility.
  • To develop an intercity horizontal carbon compensation mechanism based on emission responsibility and abatement costs.
  • To mitigate carbon inequality stemming from intercity trade and promote synergistic emission reductions.

Main Methods:

  • Utilized a multi-regional input-output model to develop the Value-Added Captured Responsibility Allocation (VCRA) scheme.
  • Integrated emission responsibility allocation with carbon abatement costs to establish a compensation mechanism.
  • Analyzed emission responsibility distribution and carbon compensation for various Chinese cities.

Main Results:

  • The VCRA scheme offers a fairer distribution of emission responsibility between producers and consumers based on value-added capture.
  • Underdeveloped, resource-intensive cities (e.g., Yulin) bear higher export-related emission responsibilities.
  • Economically developed cities (e.g., Beijing, Shanghai) are typically net payers in the carbon compensation mechanism.

Conclusions:

  • The VCRA scheme provides a more equitable approach to allocating trade-embodied carbon emission responsibility.
  • The proposed carbon compensation mechanism can help address carbon inequality and support carbon neutrality goals.
  • Fair allocation and compensation mechanisms are vital for coordinated emission reductions in China's intercity trade.
