Question

Cellular respiration and its relation between with glycolysis

Answer 1

⤵⤵⤵⤵⤵⤵⤵⤵⤵
Glycolysis is one component of cellular respiration that's catabolic and doesn't require oxygen (features unique to glycolysis; other pathways in cellular respiration require oxygen). ... Theconversion creates energy in the form ofATP, or adenosine triphosphate. 4 ATP and 2 NADH are generated during glycolysis.

Answer 2

Cellular respiration is the process by which your body converts biochemical energy from nutrients in the food you consume into energy that's usable by the body. It's the broad term that describes the set of metabolic reactions and processes that occur in the body that allow us to utilize food as an energy source.

Cellular respiration was the bank in our example because it took one large bill and broke it down into smaller bills, which were used for different activities. Cellular respiration oxidizes food into energy in the form of ATP, adenosine triphosphate. ATP in our example was the change given to us by the bank. ATP is used as energy at the cellular level in our bodies.

NADH is also a form of cellular energy, and while it's not as important in our lesson as ATP is, it is still a byproduct of cellular respiration. NADH stands for nicotinamide adenine dinucleotide, but you can just remember it as NADH for now.

Glycolysis

Glycolysis is one of the main processes involved in cellular respiration. Glycolysisis the pathway that converts sugar into energy, or glucose (C6H12O6) into pyruvate (CH3COCOO), generating ATP during the conversion.

An important term to know is catabolism. Catabolism is the breaking down of larger molecules into smaller ones (conversely, anabolism is the building of larger molecules from smaller ones). Glycolysis is catabolic; it breaks down glucose, a 6 carbon sugar into pyruvate, a 3 carbon sugar. The truth is in the name: glyco for glucose, and lysis, Greek for 'to unbind'. Glycolysis literally means 'breaking down glucose'.

Glycolysis occurs in the cytosol of the cell: the cytosol is the fluid component of the cytoplasm, the area inside a cell's membrane which contains the organelles. Glycolysis does not need oxygen to occur; it is completely independent of molecular oxygen and can proceed without it. However the energy byproducts, ATP and NADH, do require oxygen to be utilized.
