The principal role of simple sugars (i.e. simple carbohydrates) in living organisms is to create cellular energy.
<h3>What are simple carbohydrates?</h3>
Simple carbohydrates (e.g. glucose, fructose) are a special class of macromolecules composed of only one monosaccharide unit, which serve as a source of energy for cellular respiration.
In conclusion, the principal role of simple sugars (i.e. simple carbohydrates) in living organisms is to create cellular energy.

The true statements are:
1) Catabolism is the process in which complex substances are broken down, yielding a net output of energy.
Catabolism reactions break down macromolecules (lipids, proteins, nucleic acids and sugar) into smaller units that can be used for further reactions, for energy, for the synthesis of new polymer molecules or be simple waste products.
2) Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways.
Metabolism combine all chemical reactions of an organism. Functions of metabolism include: providing energy form food molecules, synthesis of building blocks of the cell, elimination of the waste products.
3) Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides.
Anabolic reactions are opposite of those in catabolism: these reactions require energy (endergonic processes) for the synthesis of necessary molecules for the cells. That energy is the product of catabolic reactions.
Answer:
B, C, Dand E are all correct
Explanation:
Why B is correct- The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell and separates the cytoplasm (the contents of the cell) from its surrounding environment. It is selectively permeable, which means that it only lets certain molecules enter and exit.
Plants, animals, and bacteria have a cell membrane. Why d is correcect
Why C is correct- The cell membrane is not a solid structure. It is made of millions of smaller molecules that create a flexible and porous container. Proteins and phospholipids make up most of the membrane structure.
Why E is correct- The plasma membrane is primarily composed of phospholipids arranged in a bilayer, with the hydrophobic tails on the interior of the membrane, and the hydrophilic heads pointing outwards
Why A Is Not correct- It is very fragile and its role is to hold the cell together and to help control what substances can get in and out. It is partially permeable, allowing only some substances to pass through it. The membrane has a complex structure consisting of a phospholipid bi-layer and different types of proteins.
Based on the symptoms present, he could be experiencing hyperglycemia.
Answer:
A pan of boiling water being heated on the stove
Explanation:
In this scenario, energy can easily be lost in the form of steam / water vapor so energy can be lose to the environment
