How do proteins utilize the energy from ATP?
Rashid [163]
Hello.

TP is a molecule with adenosine and three phosphate groups attached to it (adenosine triphosphate). To get energy from ATP, one of the bonds between the phosphates is broken, yielding energy and the molecule ADP - adenosine diphosphate, a molecule with adenosine and two phosphates. 

<span>In order to 'recharge' the molecule, a phosphate group is re-attached to ADP by ATP-synthase to yield ATP. In other words, energy is stored in the bonds between phosphates, and breaking the bond releases that energy.

What equipment should a food worker use to reheat a baked potato?
sp2606 [1]

If you want to reheat potatoes that are already cooked on a pan or fried, they may mash or dry, especially if they are fried. Better to avoid this practice for taste reasons, even if we can possibly heat them in the pan.


How to do?

To reheat potatoes boiled in water or steam, fry them in the pan: this is the best way to get the right result to taste, and you can also heat them in the microwave. cutting them into pieces so that reheating is easier and more uniform.

increasing intracellular cAMP leads to smooth muscle relaxation by: Group of answer choices inhibiting IP3 channels, leading to
kirza4 [7]

Answer:

1. Inhibiting IP3 channels, leading to decreased Ca2 in the sarcoplasm and reduced contraction.  

2. Increasing the relative activity of MLCP, leading to a decrease in tension.

3. Activating K channels, increasing K leaking out of the cell which hyperpolarizes it and decreases the likelihood of Ca2 entry.

Explanation

In smooth muscle, cyclic AMP (cAMP) mediates relaxation because cAMP inhibits a specific kinase required for myosin light chain protein (MLCP) phosphorylation, thereby triggering contraction in the smooth muscles. It has been shown that cAMP inhibits 1,4,5-trisphosphate (IP3)-dependent calcium ions (Ca 2+) release by activation of the cGMP-dependent protein kinase (PKG). PKG proteins act to modulate Ca2+ oscillations by stimulating sarcoplasmic Ca2+-ATPase membrane proteins, increasing Ca2+ in the sarcoplasmic reticulum stores and Ca2+ efflux from the cells, and activate voltage-gated potassium (K) channels, thereby leading to membrane hyperpolarization and reducing Ca2+ entry through Ca2+ channels.
