Why might it be important to move nutrients into a cell even when the concentration gradient is going the opposite direction?

Answers

Answer 1

I hope it can help you a lots Thanks.

Introduction

Passive transport(Opens in a new window) is a great strategy for moving molecules into or out of a cell. It's cheap, it's easy, and all the cell has to do is sit there and let the molecules diffuse in. But...it also doesn't work in every situation. For instance, suppose the sugar glucose is more concentrated inside of a cell than outside. If the cell needs more sugar in to meet its metabolic needs, how can it get that sugar in?

Here, the cell can't import glucose for free using diffusion, because the natural tendency of the glucose will be to diffuse out rather than flowing in. Instead, the cell must bring in more glucose molecules via active transport. In active transport, unlike passive transport, the cell expends energy (for example, in the form of ATP) to move a substance against its concentration gradient.

Here, we’ll look in more detail at gradients of molecules that exist across cell membranes, how they can help or hinder transport, and how active transport mechanisms allow molecules to move against their gradients.

The people in his family tend to be larger than average, and Elliot's weight  is above average. Should Elliot be considered fit Yes, fitness is about having an active, healthy lifestyle. Option first is the correct answer.

A healthy active lifestyle is a way of living that includes frequent exercise and nutritious eating to improve overall health. It's not about gaining peak performance or elite athlete status.

Physical activity can help you regulate your weight, reduce your risk of disease, strengthen your bones and muscles, and increase your ability to do daily tasks.

Fitness has five components: (1) body composition, (2) flexibility, (3) muscular strength, (4) muscular endurance, and (5) cardio-respiratory endurance. A well-balanced exercise regimen should include exercises that address all aspects of fitness that are related to health.

Thus, option first is the correct option.

Why is it important to know if a doctor or medical facility is
"in-network"?
It tells you if they are able to accept new patients.
It allows you to know if they are certified to practice medicine in
your location.
Your health insurance plan will pay less for their services after
your deductible is met.
Your health insurance plan will pay a greater percentage of their
costs after your deductible is met.

Answers

Explanation:

The Importance of Staying In-Network

Make sure you use doctors and service providers that are in-network:

It will significantly reduce your out-of-pocket medical expenses, and

Ensure any costs you incur are applied towards your plan's deductible and out-of-pocket maximum (out-of-network costs don't count).

Ask "Is this in my network?"

When making an appointment or scheduling a procedure, the most common question patients ask is "Do you take my insurance?" While many doctors and hospitals will accept your insurance, it doesn't mean they are in your network. And going out-of-network is expensive.

Instead, ask "Is this in my network?" And, if you're in the ER or hospital, be sure to write "only use in-network care" on all paperwork you sign. 

As the insurance policy holder, it's your responsibility to make sure you only use in-network providers and facilities. So you should always verify in-network coverage. 

What if my doctor/provider isn't covered?

For many, determining whether your primary care physician and health care providers are in-network is a key factor in selecting a plan. Ideally, your preferred doctor and preferred health plan line up. 

Sometimes a tough decision has to be made: Do I go with my preferred plan (and find a new doctor) or select a more expensive plan that covers my doctor? 

Only you can determine what will best serve you and your family in this situation. Are you financially able to take on higher costs? Will there be discontinuity in care?

Did you know...? Even if you choose the plan that covers your doctor, it's not unusual for doctors to enter or decide to leave a health insurance network.
