Describe how the shape of the insulin receptor allows glucose to get into the cell
Aloiza [94]

Type 1 Diabetic here! I can help!! so basically the receptor for insulin is a large protein that binds to insulin and passes its message into the cell. It has several functional parts. Two copies of the protein chains come together on the outside of the cell to form the receptor site that binds to insulin.

I hope this helped :)

When a singly ionized potassium ion moves through a channel in the membrane passing from the outside to the inside, what is the
Korolek [52]

The magnitude of the work done by the electric field of the membrane is <u>W = 1.28 × 10⁻²⁰ Joules</u>.

We start with the necessity to take into account a value for the voltage present there in order to solve this problem by first considering that the membranes have two layers, one internal and one external, each responsible for producing a potential difference between the two levels.

As a result, in order to find a solution, it is necessary to take into account the potential difference between the two surfaces. In this instance, we'll assume a particular value for the load, but the recipient is free to substitute a different value if they prefer.

The product of the potential difference and the charge is used to define the work that an electric field performs. The charge of the potassium ion will be equal to that of its electron, so,

q = 1.6 × 10⁻¹⁹ Coulombs

Then the Work would be:

W = Vq

Here,

v = Potential difference

q = Charge

The 80mV potential difference we will have is quantified as follows:

W = (80mV (1V/1000mV))( 1.6 × 10⁻¹⁹ C)

W = 1.28 × 10⁻²⁰ Joules is the amount of work that the membrane's electric field has produced.

Plz help!!<br><br> List 3 ways that scientists and engineers develop, use, and refine models
julia-pushkina [17]
These are some ways how scientists and engineers develop, use and refine models.

1. Imagine. They have to know what exactly trying to model. They have to imagine and brainstorm what are the things to be considered.

2. Reason. Next, they need to answer the questions brought  from their brainstorming. They need to be able to reason out.

3. Calculate and Predict. Once they know it, that's the time they can start modelling and calculate - and predict.

Which is not the defining characteristic of an acid?
Diano4ka-milaya [45]

Taste bitter  is not the defining characteristic of an acid.

<h3>What is the definition of acids?</h3>

Acids are a type of substance that is very present in our daily lives. For Chemistry, they are substances that release H+ ions in an aqueous solution, decreasing its pH.

In this case, is a characteristic of an acid the turn litmus red, reacts with bases to form salts and react with metals to form H2 gas.
