What is an electromagnet? What are the parts of an electromagnet? How is an electromagnet useful when compared to a permanent ma
kondaur [170]

Answer:

Explanation:

The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.

During gylcosis what is the source of the chemical energy that is captured in ATP
Vesna [10]

Explanation:

The breakdown of glucose.

During glycolysis, enzymes act on the substrate, glucose. The covalent bonds of the macromolecule contain energy that is released and stored within ATP.

Glycolysis occurs in the cytoplasm; here, 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules.

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP
