Answer:
Explanation:
ATP can be described as the unit for energy. Cellular processes that can involve ATP/energy are
1) Respiration: This involves the cells obtaining ATP by means of combining oxygen and glucose.
2) Metabolism: This is the building up (anabolism) and breakdown down (catabolism) process. Generally, anabolism requires ATP while catabolism releases ATP.
3) Active transport: This requires ATP to move substances or molecules across the cell membrane from a region of lower concentration to a region of higher concentration.
4) DNA replication: ATP is required to sustain replication of DNA at the replication fork during.
5) processes in the cell cycle: ATP is required for the S phase and the mitotic phase of the cell cycle.
6) Ion transport: Ion transport also requires the use of ATP to transport ions across the membrane of cells
Active transport requires that the cell move engegy that it has obtained the food to move the molecule threw the cell membrane.The passive transport doesn't required as much energy for the molecule to move....
Nematodes are wormlike organisms which can be seen with naked eye, live in water-filled pore spaces in the soil. Nematodes are in large number in the upper soil layers where organic matter, plant roots, and other resources are most abundant.
The functions of nematodes:
- Free-living nematodes decompose organic material into nutrients and cycled them in the soil by feeding on some bacteria and fungi.
- Nematodes help in distributing bacteria and fungi through the soil and along roots by carrying live and dormant microbes.
- They used as food for higher predators, soil microorthropodes.
- They eat disease-causing organisms, thus suppress their growth.
- They acts as potential bio- control agents.
Answer: Ligand gated channel
Explanation:
Ligand gated channel is an essential membrane protein that has pores and allows the passage of specific ions across the plasma membrane when it is activated by a specific chemical . Examples of such ions that pass through Ligand gated channels are Sodium ions, Potassium ions, Calcium ions. Ligand gated channels are found in extensions of the nerve cells.
