Which molecule provides the activation energy that starts glycolysis? (Not which molecule is broken down during glycolysis) (1 point)
• АТР
O sugar
• water
• carbon dioxide
ATP
To find the molecule that provides the activation energy that starts glycolysis, let's first understand what activation energy is. Activation energy refers to the minimum amount of energy required for a chemical reaction to occur. In the case of glycolysis, the activation energy is provided by a molecule that helps initiate the process.
In glycolysis, the molecule that provides the activation energy is ATP (adenosine triphosphate). ATP is commonly known as the energy currency of the cell because it stores and releases energy during various cellular processes.
During the initial steps of glycolysis, ATP is used to phosphorylate glucose, converting it into glucose-6-phosphate. This phosphorylation reaction requires energy, which is supplied by breaking one of the phosphate bonds of ATP, releasing a phosphate group and producing adenosine diphosphate (ADP). This ATP hydrolysis provides the activation energy necessary to initiate the glycolysis pathway.
So, to answer your question, the molecule that provides the activation energy that starts glycolysis is ATP.
