A) Glucose, a small molecule, can diffuse between the phospholipids. B) Glucose requires both a membrane protein and ATP energy in order to enter or exit a cell. C) Glucose, a nonpolar molecule, can pass freely across the phospholipid bilayer from high to low concentration. D) Glucose is a large, hydrophilic molecule and must use a channel protein to enter or exit a cell, but does not require energy.

Answer:

D) Glucose is a large, hydrophilic molecule and must use a channel protein to enter or exit a cell, but does not require energy.

Explanation:

Glucose is a polar, large, and hydrophilic molecule that cannot easily diffuse the cell membrane. It moves across the membrane through a mechanism known as <u>facilitated diffusion</u>. In this process, a carrier protein attaches itself to glucose molecule and transport it without any use of ATP. Instead, the movement is driven by concentration gradient. An example is the diffusion of glucose in red blood cells.

Kobotan [32]

Answer:

The correct answer would be B) enclosed in a protein capsule

Almost all living cells contain DNA as their genetic material. DNA control and coordinates the function of the cell. The two cells also must contain the DNA.

Cellular respiration refers to the set of biochemical reactions by which the cell generates ATP or energy. All the living cells produce energy through cellular respiration, however, they may utilize the aerobic or anaerobic form of respiration.

A ribosome is found in all the living cells including animal cells, plants, bacteria et cetera. They form the site for protein synthesis in all the cells.

The protein capsule is not a universal feature of all living cells. Thus, it may be present in one cell type and absent in another cell type.

What do the letters Y and Z represent?
Temka [501]

Answer: Y represents carbon and z is oxygen which gives CO2

Explanation: To photosynthesis to occur Carbon has to reacts with oxygen to give carbondioxide (Co2) which then combines with hydrogen (H2) and oxygen to give water (H20) the reaction gives glucose (C6H12O6).

Equation for photosynthesis = 6CO2+6H20- C6H12O6

Nostrana [21]

Answer:

Trichromatic vision.

Explanation:

Trichromatic theory may be defined as the theory that posses of three independent channels that are used to convey the color information. They are derived from the three different cone cells.

The television also produce three primary colors by the use of trichromatic theory. The receptor or these colors in human are greater than three as different colors have different intensity of light.  The opsin protein plays an important role in the trichromatic vision.

Thus, the answer is trichromatic vision.
