Phosphoryl-transfer potential is the ability of an organic molecule to transfer its terminal phosphoryl group to water which is an acceptor molecule. It is the “standard free energy of hydrolysis”.
Explanation:
This potential plays a key role during cellular energy transformation by energy coupling during ATP hydrolysis.
A compound with a high phosphoryl-transfer potential has the increased ability to couple the carbon oxidation with ATP synthesis and can accelerate cellular energy transformation.
A compound with a high phosphoryl-transfer potential can readily donate its terminal phosphate group; whereas, a compound with a low has a lesser ability to donate its phosphate group.
ATP molecules have a high phosphoryl transfer potential due to its structure, resonance stabilization, high entropy, electrostatic repulsion and stabilization by hydration. Compounds like creatine phosphate, phosphoenolpyruvate also have high phosphoryl-transfer potential.
<h3><u>Answer;</u></h3>
absorbed by Earth’s core
When energy from the sun reaches Earth, it is not <em><u>absorbed by Earth's core.</u></em>
<h3><u>Explanation;</u></h3>
- <em><u>The energy from the sun reaches the earth, such that 23 percent of the incoming solar radiation is absorbed by the atmosphere by water vapor, dust and ozone. </u></em>
- <em><u>48 percent of the solar energy is absorbed by the earth's surface, this translates to 71 percent of the energy which is absorbed by the systems of the Earth.</u></em>
- <em><u>The remaining 29 percent is reflected back to space by clouds, atmospheric particles etc. </u></em>
Answer:
1.
Explanation:
Xylem cell is a plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.
2. Phloem is the vascular tissue in charge of the transport and distribution of organic nutrients. The phloem is also a pathway to signaling molecules and has a structural function in the plant body.
3. Stomata are composed of a pair of specialized epidermal cells referred to as guard cells. Stomata regulate gas exchange between the plant and environment and control water loss by changing the size of the stomatal pore.
4. Guard cells optimize leaf gas exchange in response to changing environmental conditions and their turgor is controlled by alterations in atmospheric CO2 concentration, light intensity, humidity, and the drought hormone abscisic acid.
