Answer:

Explanation:

A. False - A symporter system requires that one of the molecules to be transported using passive transport.

B. True - The Na+ will move down the established concentration gradient releasing energy to facilitate movement of sucrose against its concentration gradient. This is known as secondary active transport.

C. False - sucrose moves through ion channels not by diffusion to better control its movement across the membrane.

D. True - Movement of molecules against their concentration gradient thus requiring energy input is known as active transport.

E. False - One of the molecules needs to be moving against its concentration gradient.

F. False - A Uniporter system allows the binding and transport of a single molecule at a time. A symporter allows simultaneous binding and transport of Na+ and sucrose molecules.

Vedmedyk [2.9K]

Answer:

hemoglobin will bind more oxygen when the partial pressure is low than when the partial pressure is high.

Explanation:

Binding of hemoglobin to oxygen is regulated by several factors. However, the partial pressure of oxygen is the most important factor that determines how much oxygen will bind to hemoglobin. When the partial pressure of O2 is high, hemoglobin binds with large amounts of O2. On the other hand, when the partial pressure of O2 is low, hemoglobin is only partially saturated.

Therefore, the greater the partial pressure of oxygen, the more O2 will bind to hemoglobin until saturation is reached. This is why a lot of O2 binds to hemoglobin in pulmonary capillaries where the partial pressure of oxygen is high.

What component of the circulatory system is at the tissue level? a. blood b. white blood cell c. heart d. hemoglobin

nata0808 [166]

Answer;

A. Blood

Explanation;

The main organs of the Circulatory system are the heart, the brain, the lungs. There are other key things like arteries, veins, and capillaries but they are not organs.

The major tissues in the circulatory system are the epithelial, muscle, nervous, and connective tissues.

Blood is the main connective tissue in the circulatory system, but it's a liquid connective tissue. Blood tissue is in the same family as bone and cartilage, but instead it has a liquid medium that holds it together.

Select all the molecules that have stored potential energy and that can be used in aerobic respiration to generate atp.

Masteriza [31]

Carbohydrates, lipids, and protein have potential energy, and can be used in aerobic respiration to generate .

Carbohydrate- A carbohydrate is a naturally occurring substance or a derivative of one, made composed of molecules of carbon, hydrogen, and oxygen. The most prevalent organic compound is a carbohydrate, and all life depends on them.

Lipids- Fatty, waxy, or oily molecules are referred to as lipids. They are soluble in organic solvents but insoluble in polar solvents like water.

Protein- Large, intricate molecules known as proteins serve a variety of vital functions in the body. They are crucial for the construction, operation, and control of the body's tissues and organs and carry out the majority of their job inside cells.
