na and k both use to passively diffuse across the plasma membrane. leak channels voltage-gated channels facilitated diffusion exocytosis carrier-mediated transport

Answers

Answer 1

Both Na and K use passive diffusion across the plasma membrane to leak channels.

The plasma membrane, also known as the cell membrane, is the membrane that separates the interior of a cell from its external environment. It may be found in all types of cells. A cell wall connects the plasma membrane to the outside of both bacterial and plant cells. The plasma membrane protects the cell from its surroundings while simultaneously controlling cellular mobility and sending signals. The plasma membrane, according to the fluid mosaic model, is a patchwork of phospholipids. Non-gated ion channels are ones that are always open. Because they simply allow ions to pass through the channel without causing any damage.

Answers

The heat produced by a combustion of 125g of methanol under standard state of the condition is 2836.29 kJ. The combustion reaction of methanol is 2CH₃OH+3O₂→2CO₂+4H₂O

The value for standard enthalpy of the combustion of a methanol is ΔH°=-726.1kJ/mol. It means that 1 mole of methanol on combustion releases 726.1 kJ of energy. First, we need to find molar mass of CH₃OH.

The molar mass of CH₃OH is

Molar mass=12+(4×1)+16

=12+4+16

=32g/mol

And the number of moles for CH₃OH is

moles=125g×(1 mol/32g)

moles=3.9062 mol

For one mole, we have 726.1 kJ of energy. Hence, energy for 3.9062 mol is

How does the strength of the imfs in water compare to the strength of the imfs in ethanol?.

Answers

The strength of intermolecular forces in water is greater than ethanol.

How is the strength of the intermolecular forces in water stronger than the intermolecular forces in ethanol?

Water has a stronger intermolecular force than ethanol. Because oxygen is bonded with two H-atoms in [tex]H_{2}[/tex]O, the hydrogen-ethanol bond contact is stronger than that of ethanol. Carbon has an electronegativity of 2.5, hydrogen has an electronegativity of 2.2, and oxygen has an electronegativity of 3.44.

Because O in ethanol is coupled to one C and one H atom, the electronegativity difference between O and H is therefore somewhat larger than the electronegative difference between O and C. As a result, oxygen in [tex]H_{2}[/tex]O generates a larger amount of negative charge than oxygen in ethanol.

Answers

At the end of the electron transport chain, two protons are removed from glucose molecules and combined with two electrons and two oxygen molecules to create two molecules of water.

The protons are removed from glucose molecules during the process of oxidative phosphorylation when the electrons that have been passed along the electron transport chain are used to reduce two molecules of oxygen to water.

This process is known as oxidative phosphorylation and is powered by the energy released from the oxidation of glucose molecules. The protons are removed from the glucose molecules during glycolysis and the Krebs cycle, and they are carried to the electron transport chain where they are used as a source of energy.

Though NaBH4 and LiAlH4 are similar, NaBH4 is less reactive. Esters, amides, acids, and nitriles are largely unaffected; its power is limited to reducing aldehydes, ketones, and acid chlorides to alcohols.

Because the hydride ion can attack the planar carbonyl group on either face, the reduction of unsymmetrical ketones with LiAlH4 or NaBH4 results in the production of two stereoisomers: A racemic mixture of enantiomers results from the absence of any additional chiral centers.

To do this, he constructs three identical rockets and then fills two of the rockets with varying amounts of sand to add mass. He then launches the rockets one at a time and times how long they are able to stay airborne.What is the test variable (independent variable) in Omar's experiment? A. the materials out of which the rockets were made B. the time the rockets remain airborne C. the force with which each rocket is launched D. the masses of the model rockets Write the number 476 ineach form.Word:Expanded: (12)3+ (24+9).

The following images show five planets in our solar system. Rank these planets from left to right based on their average surface (or cloud-top) temperature, from highest to lowest. (Not to scale.)Highest -- Mercury, Earth, Mars, Jupiter, Neptune -- LowestNotice that, for these five planets, temperature correlates with distance from the Sun: the closer to the Sun, the hotter the planet. Remember, however, that this is not always the case, because a planets temperature also depends on its reflectivity and on the strength of its greenhouse effect (if any). For example, the greenhouse effect gives Venus a higher average temperature than Mercury, even though Venus is nearly twice as far from the Sun. what tool does autocad use to solve the problem of very small details that are difficult to see in a large drawing?
