Answer:
C. ATP is generated
Explanation:
The Entner-Doudoroff pathway is one of the three glycolytic pathways that breakdown glucose into pyruvate. The Entner-Doudoroff pathway is the most common glycolytic pathway in microbes present in the soil such as <em>Rhizobium, Azotobacter,</em> etc. 
The Entner-Doudoroff pathway forms glucose 6-phosphate from glucose which in turn is oxidized into 6-phosphogluconate. The 6-phosphogluconate finally forms pyruvate and glyceraldehyde 3-phosphate through a series of reactions. The glyceraldehyde 3-phosphate can enter the Embden-Meyerhof pathway to form one more molecule of pyruvate. During the Entner-Doudoroff pathway, one molecule of ATP and one NADPH are formed along with the formation of one molecule of each pyruvate and glyceraldehyde. 
 
        
             
        
        
        
Answer:
Explanation:
Muscle contraction is stimulated by the movement of an action potential moving along a nerve fiber to the muscles. This event follow some series of process before being stimulated.
1. The impulse arrives at the synapse and travels through the transverse tubules.
2. The muscle impulse reaches the sarcoplasmic reticulum and calcium is released.
3. Calcium floods the sarcoplasm and binds to troponin molecules leaving active sites.
4. Tropomyosin molecules bind to exposed active sites, linking actin and myosin.
5. Thin filaments are pulled over the thick filaments.
6. The muscle fiber shortens and contracts.

NAD+ accepts a hydrogen ion (H+) and two electrons (2e−), as it becomes reduced to NADH + H+. The NADH moves to the electron transport chain and donates a pair of electrons (becomes oxidized) to the first compound in the chain.
