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.

How many grams are NaCl are required to prepare 200 mL of a 3.10 M solution?
rodikova [14]

The mass (in grams) of NaCl required to prepare the solution is 36.27 g

<h3>What is molarity?</h3>

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

<h3>How to determine the mole of NaCl</h3>
  • Volume = 200 mL = 200 / 1000 = 0.2 L
  • Molarity = 3.1 M
  • Mole of NaCl =?

The mole of NaCl in the solution can be obtained as follow:

Molarity = mole / Volume

Cross multiply

Mole = Molarity x Volume

Mole of NaCl = 3.1 × 0.2

Mole of NaCl = 0.62 mole

<h3>How to determine the mass of NaCl </h3>

We can obtain the mass of NaCl needed to prepare the solution as follow:

  • Molar mass of NaCl = 58.5 g/mol
  • Mole of NaCl = 0.62 mole
  • Mass of NaCl = ?

Mole = mass / molar mass

Cross multiply

Mass = mole × molar mass

Mass of NaCl = 0.62 × 58.5

Mass of NaCl = 36.27 g

What are the reactants in cellular respiration? what are the products?
Gwar [14]
Cellular respiration is the process of releasing energy from the food that one had taken. The reactants of the cellular respiration were both oxygen and glucose. The main product of this process would be ATP (adenosine phosphate) but could also be H2O and CO2.
