Glycolysis investment phase structures
WebThe first step of glycolysis in which energy is utilized is the conversion of D-glucose into glucose-6-phosphate. This is the first reaction of the glycolysis that is catalyzed by the … WebOct 8, 2024 · The pay-off phase is where ATP is produced. The first five steps of the glycolysis reaction are known as the preparatory or investment phase. This stage consumes energy to convert the glucose molecule into two molecules three-carbon sugar molecule. Step 1. The step one in glycolysis is phosphorylation.

WebStep 1. The first step in glycolysis (Figure 9.1.1) is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose. WebGlycolysis begins with the six carbon ring-shaped structure of a single glucose molecule and ends with two molecules of a three-carbon sugar called pyruvate. Glycolysis consists of two distinct phases. The first part of the glycolysis pathway traps the glucose molecule in the cell and uses energy to modify it so that the six-carbon sugar ...
Web4) Why is glycolysis described as having an investment phase and payoff phase? a. it both splits molecules and assembles molecules b. it attaches and detaches phosphate groups c. it uses glucose and generates pyruvate d. it uses stored ATP and then forms a net increase in ATP WebThe first phase of glycolysis requires energy, while the second phase completes the conversion to pyruvate and produces ATP and NADH for the cell to use for energy. ...

WebSummary of Glycolysis 1. One glucose (6C) converted into 2 pyruvates (3C) -- no carbon atoms are lost. However, the molecules have less potential energy since glucose has been partially oxidized. 2. Four ATP produced but net yield of 2 ATP for use by cell - other 2 used to split more glucose in initial "priming" reactions. ATP is produced using substrate-level …
