The breakdown of food molecules, such as glucose in the absence of oxygen is called?

If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water. This process is called aerobic respiration because it requires air (oxygen). In the absence of oxygen, the cell uses a process called anaerobic fermentation. or simply fermentation.

Answer: The complete glucose breakdown is a series of chemical reactions representing transformation of glucose to adenosine triphosphate during the normal phases of aerobic cellular respiration. It is mostly done inside the mitochondria to release the maximum amount of energy.

Identify the model that best represents the plasma membrane of a hypothetical cell that exists in a nonaqueous environment and w

Klio2033 [76]

Answer:

The models are missing in the question. The models along with the question is provided in the attachment below.

The answer is : Model A represents the Plasma membrane.

Explanation:

According to the question, model A represents the plasma membrane. The reasons are :

(a). In the model A, the bilayers consists of two leaflets of the amphipathic lipid molecules. Here the polar head groups is in contact with the intra cellular or the extra cellular non aqueous phase, where the non polar tails are facing each other constituting the hydrophobic interior of the membrane.

(b). Lipid are not rigid as well as static structure. In the lipid bilayer, the lipid molecule are able to rotate around their axis freely and diffuse laterally with each leaflet.

(c). The plasma membrane acts as the selective plasma membrane.

A solution that contains more solute than it would normally hold at that temperature is said to be

Vitek1552 [10]

Answer: supersaturated

Explanation: A supersaturated solution is a solution in which the dissolved solute is more than the solvent can hold at that particular temperature.

A solution is a substance which sontains a dissolved solute. A solution can be saturated, unsaturated or supersaturated.

A saturated solution contains the maximum amount of dissolved solute a solvent can hold at that temperature.

An unsaturated solution contains less amount of solute than the solvent can hold at that temperature, this means that more solute can still dissolve in the solution.

A supersaturated solution contains more solute that can be dissolved in the solvent at that temperature.

How are the cells in multicellular organisms different from those in single-celled organisms?

Mrac [35]

Answer: Option D) Cells in multicellular organisms are specialized to perform certain functions.

Explanation:

Multicellular organisms include humans, reptiles, birds etc. While unicellular organisms include amoeba, paramecium etc

From the examples given, the cells of multicellular organisms are specialized in function in that:

- cells that perform similar functions are put together as tissues, organs or system e.g digestive system consists of the similar cells that help to break down food into pieces

On the other hand, unicellular organisms possess just one cell that do all the functions.

Thus, the difference between both is that cells in multicellular organisms are specialized to perform certain functions.
