Oxaloacetate
Two molecules of NADH are generated after one cycle of the TCA (Krebs) cycle.
Nucleotides, lipids, and some amino acids are not directly generated via the TCA cycle or electron transport chain. They are derived from intermediates of these processes but have different metabolic pathways for their synthesis.
Anabolic reactions in the TCA cycle involve the production of intermediates that can be used for the synthesis of molecules such as amino acids, fatty acids, and nucleotides. For example, oxaloacetate produced in the TCA cycle can be used for gluconeogenesis or for the synthesis of amino acids. These reactions require energy input and are generally biosynthetic in nature.
No, the TCA cycle (also known as the citric acid cycle or Krebs cycle) does not directly generate water. Instead, it is a series of chemical reactions that converts acetyl-CoA into carbon dioxide, producing ATP and electron carriers like NADH and FADH2 in the process. Water is mainly generated through oxidative phosphorylation in the electron transport chain.
The substrates of the TCA (tricarboxylic acid) cycle, also known as the Krebs cycle, primarily include acetyl-CoA, which is derived from carbohydrates, fats, and proteins. The main products of the cycle are carbon dioxide (CO2), NADH, FADH2, and ATP (or GTP). These products are crucial for cellular respiration, as NADH and FADH2 are used in the electron transport chain to generate additional ATP.

The compound generated in the TCA (tricarboxylic acid) cycle is citrate. This cycle is also known as the Krebs cycle or citric acid cycle. It is a series of chemical reactions that produce energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.

No, oxygen is not directly used in the TCA (tricarboxylic acid) cycle. The TCA cycle, also known as the citric acid cycle, is a series of chemical reactions that occur in the mitochondria and is primarily involved in generating energy from carbohydrates, fats, and proteins. Oxygen is used in the electron transport chain, which is a separate process that follows the TCA cycle and is responsible for the final stages of cellular respiration.
Yes, the TCA (tricarboxylic acid) cycle is another name for the Krebs cycle or citric acid cycle. These terms are used interchangeably to describe the same metabolic pathway that occurs in the mitochondria of cells, producing ATP and carbon dioxide as part of aerobic respiration.
It means "Filling up"... If we are talking about the TCA cycle, which I am assuming we are. A set of reactions, one of which is the glyoxylate cycle supports the TCA cycle with intermediates that are used in making other molecules, therefore filling in the intermediate that were used in other reactions. For example, Citrate is used to make Fatty Acids and Cholesterol. When citrate is pulled from the TCA cycle to make these molecules fewer citrate molecules will go through the TCA cycle making less succinate and there for less oxaloacetate. The glyoxylate cycle makes up for this deficit by making succinate, fumarate, and malate which will proceed to complete the TCA cycle.

The kerb cycle is also known as the citric acid cycle or the TCA cycle.
