The main components of the plasma membrane contain hydrophobic and hydrophilic regions that give the membrane selective permeability. Which of the following is the
main component that creates the hydrophobic and hydrophilic regions? (3 points)
a. Cholesterol molecules creating membrane fluidity
b. Carbohydrates for cell recognition
c. Glycolipids containing hydrophobic lipid portion
d. Phospholipids containing hydrophobic fatty acids tails

Answers

Answer:

The main components that creates the hydrophobic and hydrophilic regions of the plasma membrane are phospholipids containing hydrophobic fatty acids tails.

Explanation:

Phospholipids are the main component of the cell membrane —lipid bilayer— and responsible for its selective permeability.  Each phospholipid is composed of one glycerol molecule, which forms the head, and two fatty acid tails, plus one phosphate molecule.

In the lipid bilayer, the phospholipid heads are oriented towards the surface, while the tails are located inside, allowing interaction with both polar and apolar molecules.

The hydrophilic regions of the membranes are in contact with the liquids of the extracellular and intracellular spaces, while the hydrophobic region is inside the membrane, limiting the passage of polar molecules or ions.

The other options are not correct because:

    a. Cholesterol molecules are part of the membrane, but are not responsible for the hydrophobic and hydrophilic regions.

    b. Carbohydrates for cell recognition do not determine membrane permeability.

    c. Glycolipids, like integral proteins, are part of the membrane, but do not determine the polarity of the regions.

2 The body has to always maintain a constant internal environment. For example, the hormones
aldosterone and antidiuretic hormone (ADH) help regulate the balance of bodily fluids by causing the
kidney to excrete or retain fluids and electrolytes. This constant regulation of hormones and bodily fluids
to maintain balance is an example of which cellular process?
F) Active Transport
G) Negative Feedback
H) Positive Feedback
J) Homeostasis

Answers

Answer:

H

Explanation:

I am not 100% sure but that seems like a reasonable answer

Drag the numbers to put the following steps in the correct order.
As electrons move down the ETC, a H+ gradient is made.
The Krebs cycle produces ATP, NADH and CO2.
Ht pass through the ATP synthase to make ATP.
NADH gives electrons to the ETC.
In glycolysis, glucose is split into two pyruvate and makes some ATP.

Answers

Answer:

4, 2, 5, 3, 1

4 (As electrons move down the ETC, a H+ gradient is made), 2 (The Krebs cycle produces ATP, NADH and CO2), 5 (H+ pass through the ATP synthase to make ATP), 3 (NADH gives electrons to the ETC), 1 (In glycolysis, glucose is split into two pyruvate and makes some ATP)

In glycolysis, glucose is split into two pyruvate and makes some ATP. (GLYCOLYSIS)The Krebs cycle produces ATP, NADH and CO2. (KREBS CYCLE)NADH gives electrons to the ETC. (ELECTRON TRANSPORT CHAIN)As electrons move down the ETC, a H+ gradient is made. (ETC)H+ passes through the ATP synthase to make ATP. (ATP SYNTHASE)

Explanation:

The correct steps are as follows:

NADH gives electrons to the ETC.The Krebs cycle produces ATP, NADH and CO2.In glycolysis, glucose is split into two pyruvate and makes some ATP.Ht pass through the ATP synthase to make ATP.As electrons move down the ETC, a H+ gradient is made.

What is glycolysis? Glycolysis is the process in which glucose is broken down to produce energy. It  generates two molecules of pyruvate, ATP, NADH and water. The process takes place in the cytoplasm of a cell and does not require oxygen. It occurs in both aerobic and anaerobic organisms.

Thus, these are the correct order.
