Which enzyme is used in gluconeogenesis, but NOT in glycolysis? Group of answer choices PEP carboxykinase enolase (interconverts 2-phosphoglycerate and phosphoenolpyruvate)

PEP carboxykinase

Explanation:

PEP carboxykinase is also known as Phosphoenolpyruvate carboxykinase. It is an enzyme which is used for the production of glucose from non-carbohydrate carbon substrates. This enzyme is used only in gluconeogenesis not in glycolysis because this enzyme helps in the production of glucose while glycolysis is a process in which the glucose  break down into pyruvate and ATP molecules.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
