Explanation:
For question no 19
Force (F) = 20N
distance (d) = 5m
Work = F * d
= 20 * 5
= 100 J
Now
For question no 20
D. No matter how much force is applied the object must have motion for work to be done.
Answer:
The correct answer is a cofactor for enzyme activity.
Explanation:
Carboxypeptidase is a metallo-enzyme in which zinc is present at active site. It has been accounted for by Coleman and Vallee that the protein can be deactivated by the removal of zinc and that reactive again by the expansion of zinc, cobaltous, ferrous, nickel. which suggests that zinc is acting as the cofactor for this metalloenzyme. Zinc is a cofactor for up to 300 chemicals in the body. Proteins that utilization zinc as a cofactor is known as metalloenzymes.
Thus, the correct answer is a cofactor for enzyme activity.
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.
