False,enzymatic reactions, the molecules at the beginning of the process are called substrates
Answer choices are:
A. Invalidate, because energy should not leave a closed system
B. Invalidate, because the amount of energy should stay constant
C. Validate, because an aquarium is an open system that loses and gains energy
D. Validate, because the amount of energy lost was replaced by matter.
The correct answer choice is:
C. Validate, because an aquarium is an open system that loses and gains energy.
Explanation:
As we know that, the law of conservation of energy is that the total amount of energy of an isolated system prevails to be constant, it is said to be maintained or conserved over time. This law means that energy can neither be created nor be destroyed; rather, it can only be converted or transferred from one form to another.
Answer:
1. Oxygen is the terminal electron acceptor in aerobic respiration
2. Pyruvate typically serves as the final electron acceptor during fermentation.
Explanation:
Under normal aerobic conditions, the final electron acceptor at the end of the electron transport chain is oxygen. However, fermentation occurs when there is no oxygen available. Therefore, something else must act as the final electron acceptor. In lactic acid fermentation, NADH is the electron carrier that ultimately carries them to pyruvate. Pyruvate is reduced to lactic acid, and thus, acted as the final electron acceptor.
Answer:
D. None of the above
Explanation:
all the answer choices are found in soil
Though most prokaryotes have both a cell membrane and a cell wall, there are exceptions such as Mycoplasma (bacteria) and Thermoplasma ( archaea ) which only possess the cell membrane layer. The envelope gives rigidity to the cell and separates the interior of the cell from its environment, serving as a protective filter. Hope this helped!
