Explain why glucose continues to enter a cell, even when the concentration inside the cell might be higher than outside.





How many ions can move through a protein channel per second (on average)?







Do protein channels have specificity? (i.e. Are they specific about what they let cross the membrane or can any molecule go through any channel?)





Explain how the sodium/potassium pump works. Why does this process require ATP?

Answers

Answer 1

Answer:

1)ATP. The concentration of glucose inside of a cell is higher than the concentration outside of that cell, yet glucose continues to enter the cell. ... Two solutions are separated by a selectively permeable membrane that is not permeable to glucose.

2)For transport efficiency, channels have an advantage over carriers in that up to 100 million ions can pass through one open channel each second—a rate 105 times greater than the fastest rate of transport mediated by any known carrier protein.

3)The sodium-potassium pump uses active transport to move molecules from a high concentration to a low concentration. The sodium-potassium pump moves sodium ions out of and potassium ions into the cell. This pump is powered by ATP. For each ATP that is broken down, 3 sodium ions move out and 2 potassium ions move in.

In what ways do plants use energy

Answers

Answer:

Plants use energy in multiple ways. One way they use energy is to move. Many don't realize that plants move because their exact position does not change. However, plants do shift in order to face the sun and get more light. Additionally, plants grow. For plants to get taller and larger they need to use energy.

They use a process call photosynthesis to make food. During the process the plants trap light energy with their leaves. They use the sun and carbon dioxide with Turns into sugar with creates glucose.

According to the model of the human respiratory system, how do structures in the
respiratory system interact to protect the lungs? How might a sinus infection affect the
rest of the respiratory system?

Answers

Answer: The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.

Explanation:

There are Cilia that protect the airways of the lungs from invaders and pathogens by trapping them. Sinus is present in the nose which blocks the airways while it swells.

What is the respiratory system?

The respiratory system is the system that is responsible for getting oxygen into the body and removing carbon dioxide from the body.

Together, the respiratory and circulatory systems move blood and oxygen throughout the body. The trachea, bronchi, and bronchioles are the pathways by which air enters and exits the lungs. The pulmonary arteries and veins, which attach to the heart, carry blood into and out of the lungs.

Thus, there are cilia that, by trapping invaders and diseases, defend the lungs' airways. The nose has a sinus, which obstructs the airways when it grows.

Which would conserve more energy if all humans ate only vegetables or ate only meat

Answers

Answer:

There would be more conservation of energy if human beings it only meat.  

Explanation:

this is because meat consists of a significant portion of the fat. The amount of of energy that is liberated per molecule of fat is almost twice the amount of energy that is liberated by carbohydrate or protein. As a result of this the total energy consumption will be more if human being consumes only fat. however it takes more time to digest fat as compared to that of carbohydrate and protein.

Warm water rises because it is ............ than cool water.


a) warmer

b) cooler

c) more dense

d) less dense



**Answer and I will give you brainiliest**​

Answers

Answer:

I'm pretty sure the answer is D.) Less Dense

Explanation:

Answer:

d) less dense

Explanation:

When fluids (liquids and gases) are heated, they expand and therefore become less dense. Any object or substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water.

How would the equilibrium change if the ocean became more acidic?

Answers

Answer: more H2CO3 is made

Explanation:

Acidic water of the ocean creates instability in the ocean ecosystem.

What happens when ocean become acidic?

If the acidity of ocean increases the corals can't build skeletons and the shellfish also can't build the shells which they need for protection.

Corals are particularly important because they provide homes for many other sea creatures so we can conclude that acidic water of the ocean creates instability in the ocean ecosystem.

You push on an object with an applied force. What is the "reaction" force to your push?
the object being pulled by Earth
the object moving forward
the object pushing back on you
the object being lifted up

Answers

Answer:

the object pushing back on you

Explanation:

i put b in my test and it was wrong

and did it again and got it right

According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.

The answer would be:

The object pushing back on you.
