ions?

  • The balance between the chemical and electrical forces pushing potassium through potassium channels and across the membrane is represented by the potassium equilibrium potential.
  • At the equilibrium potential of potassium, which is -80mV, there is no net movement of potassium ions.

<h3>At potassium's equilibrium potential, what happens?</h3>
  • At equilibrium, the electrical potential gradient across the membrane precisely balances the gradient of K+ concentration.
  • There is no net migration of K+ from one side to the other, despite the fact that K+ ions continue to traverse the membrane via channels.

<h3>How does potassium diffuse in order to influence the membrane potential?</h3>
  • Potassium ions will flow down their concentration gradient, or towards the exterior of the cell, because the membrane is permeable to them.
  • Although the membrane is not permeable to sodium, there is a concentration gradient that favors sodium diffusion in the opposite direction.

Rashid [163]

Answer:

The correct ecological sequence regarding this case, to answer your question: What is the correct sequence of ecological roles played by the bacterium in the situation decribed here, would be: 1. mutualism, 2. Parasitism and finally 3. Nutrient recycler.

Explanation:

Ecological balance comes when species interact, and help each other out, by carrying out tasks that the other species cannot perform. When this happens, both species benefit from the presence of the other, and thus are kept in balance. However, conditions may change that will affect this balance.

In this case, we have a bacteria and a plant that are ecologically balanced with each other: the plant provides nutrients to the bacteria, and the bacteria helps the plant by maintaining other microorganisms away. However, when the conditions of the plant change, giving the bacteria access to its insides, which are more nutrient-rich, than the outside, these bacteria do not waste time and infect the plant, until it kills, and then decomposes, the plant. Given the sequence, the first part is known as mutualism: to species sharing benefits. Parsitism, because the bacteria infected the plant and lived now off it, destroying it. And finally, nutrient recycler because the bacteria breaks down the plant, decomposes it, returning to the ecosystem nutrients that were inside the plant.

The value of n, the Hill coefficient, for hemoglobin is about _________ as great as the value for myoglobin.
ludmilkaskok [199]

The value of n, the Hill coefficient, for hemoglobin is about 2 to 3 times as great as the value for myoglobin.

Hill Equation

The two closely related equations that help to explain the binding of macromolecules to ligands are called the Hill equation. It helps to quantify the interaction between various ligand binding sites.

Hill coefficient

It is used to describe the cooperativity of ligand binding. It can be positive and negative depending on the value of the Hill coefficient. If the value of the Hill coefficient is more than one then it exhibits positively cooperative binding and if it is less than one then it exhibits negatively cooperative binding. Then there is the noncooperative binding where the Hill coefficient value is one. As for the hemoglobin and myoglobin, the values are,

  • Hill coefficient of hemoglobin is 2.7 - 3.
  • Hill coefficient of myoglobin is 1.0.

Thus hemoglobin is positively cooperative and myoglobin exhibits noncooperative binding.

aleksklad [387]
Formation of the Earth's Atmosphere. The early Earth was very different from our Earth today. The early Earth experienced frequent impacts from asteroids and meteorites and had much more frequent volcanic eruptions. There was no life on Earth for the first billion years because the atmosphere was not suitable for life.
