The biosphere, speaking generically, is all the living things -- plants and animals -- in the world.
The biosphere is the global ecosystem, the sum of all the planet's ecosystems. This includes the atmosphere (several kilometers), and the land (at least 3000 meters below ground to the depth of several kilometers). It is often referred to as the "zone of life", where all of earths organisms live.
Closed Biosphere (scientific research projects)
The Biosphere is a sealed, self-supporting ecological environment created to study diverse ecosystems in a controlled medium. Large-scale experiments on human systems (Biosphere 2, BIOS-3) were carried out from 1972 to 1991, with only limited success. None showed the capability for long-term self-sufficiency.

How did the citric acid cycle get its name what is the origin of citric acid cycle?
The conguate base of citric acid - citrate - is an important intermediate in the cycle. This is where the name "Citric Acid Cycle" comes from. It is also known as the Tricarboxylic Acid Cycle - as it involves 3 carbon acids, or the Krebs Cycle after Hans Adolf Krebs - who developed the complexities of the cycle.
What organelle does the citric acid cycle occur?
The citric acid cycle, also known as the Krebs cycle, occurs in the mitochondria of eukaryotic cells.
Citric acid forms during which part of cellular respiration?
Citric acid is formed during the citric acid (Krebs) cycle, which is the second stage of cellular respiration. In this cycle, acetyl-CoA is oxidized to produce ATP, CO2, and NADH in a series of reactions that take place in the mitochondria.
What can you do with the end product of glycolysis?
The end product of glycolysis is pyruvate. Pyruvate can be further metabolized through aerobic respiration in the presence of oxygen, entering the citric acid cycle to generate more ATP. In the absence of oxygen, pyruvate can undergo fermentation to generate ATP anaerobically.
Is urea a product of fatty acid metabolism?
No, urea is a byproduct of protein metabolism, specifically the breakdown of amino acids. Fatty acid metabolism primarily produces acetyl-CoA, which enters the citric acid cycle for energy production.
How can the same biochemical be both a reactant and product in aerobic respiration?
The citric acid cycle is a cycle.
What is the citric acid cycle also known as?
Krebs cycle (aka citric acid cycle, aka tricarboxylic acid cycle)
What is the end product of the breakdown of pyruvic acid?
The end product of the breakdown of pyruvic acid in aerobic conditions is acetyl-CoA, which enters the citric acid cycle. In anaerobic conditions, pyruvate is reduced to lactate or fermented to produce ethanol.
What is the waste product form during the Krebs cycle?
A byproduct of the krebs cycle/citric acid cycle is carbon dioxide.
What are the two other names for Krebs cycle?
Citric Acid Cycle TCA Cycle (tricarboxcylic acid cycle).
How did the citric acid cycle get its name what is the origin of citric acid cycle?
The conguate base of citric acid - citrate - is an important intermediate in the cycle. This is where the name "Citric Acid Cycle" comes from. It is also known as the Tricarboxylic Acid Cycle - as it involves 3 carbon acids, or the Krebs Cycle after Hans Adolf Krebs - who developed the complexities of the cycle.
What two molecules combine to produce citric acid in the citric acid cycle?
Acetyl-CoA and oxaloacetate combine to produce citric acid (or citrate) in the citric acid cycle. This is the first step in the cycle, also known as the condensation step.
What are the Outputs of the citric acid cycle?
The net inputs for citric acid cycle are Acetyl CoA, NADH, and ADP. The Net outputs for the citric acid cycle are ATP, NAD, and carbon dioxide.
Why is the Citric Acid cycle called a cycle?
The Citric Acid cycle is called a cycle because it is a series of chemical reactions that regenerates its starting molecule, oxaloacetate, at the end. This allows the cycle to continue repeatedly as long as there are substrates available.
What are the intermediates in the citric acid cycle?
The intermediates in the citric acid cycle are citrate, isocitrate, α-ketoglutarate, succinyl-CoA, succinate, fumarate, malate, and oxaloacetate. These intermediates undergo a series of enzymatic reactions to generate energy in the form of ATP.
What is another way to say Calvin cycle?
C6 cycle, Citric/Citric Acid cycle
What organelle does the citric acid cycle occur?
The citric acid cycle, also known as the Krebs cycle, occurs in the mitochondria of eukaryotic cells.
