<span>Our biosphere is the global sum of all ecosystems. It can also be called the zone of life on Earth, a closed (apart from solar and cosmic radiation) and self-regulating system. Geology studies the Earth, and has tendrils in all ecosystems, thus the connection to the biosphere.</span>
The cell membrane is also called selectively permeable membrane for the sole reason being it is selective in nature.
It forms a physical barrier and as a barrier between the cell and the external environment as it allows only selected necessary molecules to pass through it and at the same time prevents entry of unwanted / unnecessary substances.
It also regulates the entry and exit of molecules into and out of the cell.
The cell membrane permits the entry of vital molecules like
<span>water, oxygen, amino acids and glucose into the cell as they are crucial for various life processes and at the same time metabolic waste products are expelled through the cell membrane.</span>
Answer:
an enzyme! Keep in mind that an enzyme catalyzed the rate of a reaction. A normal reaction must climb the activation barrier independently, while the one catalyzed by an enzyme has a lower activation barrier due to added stability.
