Answer:
b. diffusion and osmosis across semi-permeable membranes
Explanation:
ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.
In the above options, the processes listed as follows require ATP to occur:
- The active transport of glucose from the small intestine to the blood
- The movement of the flagella of sperm for motility
- Exocytosis of waste substances across a semi-permeable membrane
However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.
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
Answer:
An atom with a single electron in its outermostshell
Explanation:
Protects, helps thermoregulate, provides sense of touch, helps remove waste
