What happens in the electron transport chain when one glucose molecule is broken down?
As a glucose molecule is gradually broken down, some of the breakdowns steps release energy that is captured directly as ATP. As electrons move through the electron transport chain, they go from a higher to a lower energy level and are ultimately passed to oxygen (forming water).
How many ATP molecules are made for every glucose molecule broken down?
One glucose molecule produces four ATP, two NADH, and two pyruvate molecules during glycolysis.
How many electron transport chains are there?
four
There are four complexes composed of proteins, labeled I through IV in Figure 1, and the aggregation of these four complexes, together with associated mobile, accessory electron carriers, is called the electron transport chain.
Does the electron transport chain split glucose?
Water is a byproduct made during the electron transport chain. Food molecules are broken down into glucose. Oxygen is needed to accept the electrons at the end of the electron transport chain.
How many electron carrier molecules are made per glucose in glycolysis?
2
Enzymatic ( phosphoglycerate kinase ) transfer of a phosphate group to ADP occurs forming high energy ATP molecules. 2 NADH carrier and 2 ATP molecules are formed per glucose molecule in the glycolytic pathway.
How many electron carrier molecules are made per glucose put in to glycolysis?
Thus, some of the energy released by oxidation drives the direct synthesis of ATP molecules from ADP and Pi, and some remains with the electrons in the high-energy electron carrier NADH. Two molecules of NADH are formed per molecule of glucose in the course of glycolysis.
How many ATP are produced in electron transport system?
2.5 ATP/NADH and 1.5 ATP/FADH2 are produced in the electron transport chain. Some resources will say 3 ATP/NADH and 2 ATP/FADH2, but these values are generally less accepted now.
How many ATP molecules are produced in the electron transport system?
34 ATP molecules
Electron transport chain This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP.
How many electron transport chains are there in photosynthesis?
two electron transport chains
In photosynthesis, there are two electron transport chains.
How many molecules of the following are formed from the breakdown of glucose?
1. Glycolysis: Glucose is split into two molecules called pyruvate and 2 ATP molecules are generate per molecule of glucose as well as 2 molecules of NADH. Glycolysis takes place in the cytoplasm of the cell and does not require oxygen.
How many electron carrier molecules both NADH and FADH2 are made per glucose put into glycolysis?
in glycolysis 2 ATP molecules, 2 NADH molecules, and 2 pyruvate molecules per 1 glucose molecule are produced!!! each one of the 2 pyruvate molecules continues to the link reaction, which converts it into acetyl-CoA that will be qualified to enter Krebs’ cycle…
