Which phrase best describes cellular

Akimi4 [234]

changing of stored chemical energy in food molecules to a form usable by organisms.

Explanation:

Cellular respiration involves the changing of chemical energy in food molecules to a form usable by organisms.

During the process of cellular respiration, oxygen combines with food materials in form of glucose to release useful energy needed for life to function.

Respiration can be pictured as the reverse process of photosynthesis in which chemical energy is produced.

In respiration, energy is released from the food materials.

<h3>☣ Question -:</h3>

Which of these equation is the correct one for fermentation?

❍ Glucose + oxygen → carbon dioxide + water

❍ Glucose → lactic acid

❍ Glucose → ethanol + carbon dioxide

<h3>☣ Explanation -:</h3>

To understand this first we should know what is fermentation.

<u>What </u><u>is </u><u>fermentation</u><u>?</u>

A process of chemical change in food or drink because of the action of yeast which may cause it to produce bubbles or heat, or turn sugars in it into alcohol.

<u>Equation -:</u>

$\small\sf{C_{6}H_{12}O_{6} \rightarrow2C_{2}H_{5}OH + 2CO_{2}}$

Which means

Glucose → ethanol + carbon dioxide

Hence opition c is the correct answer.

The graph shows the change in number of two populations, lions and zebras. The solid line represents the population of zebras an

<span>The graph portrays predation. The relationship shows that an increase in the population of zebra results in a subsequent increase in the lion population, and vice versa. This, therefore, means that the lion population is dependent on the zebra population due to an interaction (predation). The lion population will always be lower than that of the zebra because of the inefficiencies of energy transfer up the trophic levels (exhibited by a typical energy pyramid). </span>

Musya8 [376]

This is because not all genes are expressed at the same time, so not all the proteins are present at a certain moment. The mechanisms that cell uses to control gene expression are called regulation of the gene expression. Thanks to regulation of the genes, cells have the ability to increase or decrease the production of specific gene products such as proteins. This property is important for the adaptability of an organism because it allows the cell to express protein when needed.
