Lactose metabolism is regulated by lac operon in prokaryotic cells. When in the environment lactose is present, the cell signals the presence of lactose and synthesizes the enzyme required for the degradation of lactose. Removal of lactose from the environment leads to the termination of the enzyme synthesis. Thus, the metabolism of lactose is environment dependent.
The metabolism of lactose is also dependent on the presence of glucose. Glucose is the favorite food for bacteria. If glucose and lactose both are present in the environment, the bacterial cells prefer glucose over lactose and lactose is not metabolized. In the absence of glucose, the cells will metabolize lactose.
If its chemistry:
Hg: Mercury/Transition metal
Ni: Nickel/Transition metal
Ti: Titanium/Transition metal
Answer:
D. It is not a superordinate goal because it did not require both pet store owners to accomplish.
Explanation:
In this case, both pet stores are benefited and therefore it corresponds to a superordinate goal.
Answer:
B
Explanation:
Gas exchange provides oxygen that is required for aerobic cellular respiration. Aerobic respiration produces more ATP molecules than anaerobic respiration. This is because oxygen acts as the ultimate proton acceptor (in the Krebs/Citric cycle) in the matrix of the mitochondria to form water as the waste product. This allows a proton motive force to be created in the mitochondria that is harnessed by ATP synthase to produce ATP molecules.
