The Krebs cycle is considered an aerobic process because it is part of the process of respiration, in which oxygen is required to break down food molecules to release energy.
Since Krebs is a cycle, there is a pretty good argument that there is no "first metabolite". However, because citrate is a condensation product of OAA and acetyl-CoA, and acetyl-CoA is typically what is feeding in to the Krebs cycle, citrate could be considered the "first metabolite"
The Krebs cycle is the sequence of reactions by which most living cells generate energy during aerobic respiration. It takes place in the mitochondria, consuming oxygen, producing carbon dioxide and water as waste products, and converting ADP to energy-rich ATP.
It's called the Krebs's cycle and it consists of the steps to convert a 2 carbon sugar into CO2 and H2O. (And you don't own the genetic code to do this ... only the mitochondria do.)
This process is called cellular respiration. It occurs in three steps, glycolysis, the Krebs Cycle, and the Electron Transport Chain, in that order. Glycolysis occurs in the cytoplasm of the cell, while the Krebs Cycle and the Electron Transport Chain both take place inside the mitochondria of the cell. This is why the mitochondria is referred to as "the powerhouse of the cell."
Well for people who aren't familiar with the abbr. Nicotinamide adenine dinucleotide aka NAD acts as an electron and hydrogen carriers in some oxidation-reduction reactions in the Krebs Cycle, and flavin adenine dinucleotide aka FAD is a hydrogen acceptor molecule in the Krebs Cycle.
In the mitochondrial matrix.
Krebs cycle Electron transfer chain
aerobic respiration have 3 processes are: glycol's, Krebs cycle, electrom transport chain :)
After glycolysis and Kreb cycle, the third process is the electron transport chain, from where the most ATP are made.
Krebs Cycle .
Please think about what you're saying. You asked whether anaerobic repiration is aerobic or anaerobic. I believe you have the answer to your question embedded in your question.
Both the Krebs Cycle and the electron transport chain are in the mitochondria and they are aerobic.
Aerobic. The Krebs cycle is a way of producing ATP using oxygen. The use of oxygen for energy production means Aerobic (as opposed to Anaerobic or without-oxygen).
The Krebs Cycle
aerobic
Krebs cycle refers to the sequence of reactions that allow living cells to generate energy during aerobic respiration.
The answer is the Krebs Cycle is only one step in aerobic respiration. The Krebs cycle strips away carbon from the molecule being catabolized in order to free up electrons. These electrons then go on to the electron transport chain, which requires oxygen.
