_________ cells must be in osmotic equilibrium with their surrounding environments, because if they swell or shrink their membranes will rupture. A) Animal B) Bacterial C) Fungal Eliminate D) Plant
The right answer is A) Animal.
The cell wall prevents the cell from bursting. Animal cell does not have this structure, but it exists in plants, bacteria and fungi.
When the entry of water is in an animal cell, it is rather said that the cell is lysed and not turgid (like the cells having a wall), sometimes even until the bursting and the death of the cells. is placed in a very hypotonic solution. This bursting is due to the fact that the animal cell does not have a wall.

Identify four organelles that should be present in the eukaryotic organism and describe the function of each organelle.
Final answer:
The eukaryotic organism contains organelles such as the nucleus, mitochondria, endoplasmic reticulum, and the Golgi apparatus, which function in controlling cellular activity, producing energy, synthesizing proteins, and processing cellular products, respectively.
Explanation:
Four organelles that should be present in a eukaryotic organism and their functions are as follows:
Nucleus: Acts as the control center of the cell, housing the DNA and coordinating activities such as growth, metabolism, and reproduction.Mitochondria: Known as the powerhouses of the cell, mitochondria are where oxidative phosphorylation occurs to produce ATP, the cell's energy currency.Endoplasmic Reticulum (ER): Divided into rough ER, which is involved in protein synthesis and folding due to the presence of ribosomes, and smooth ER, which is important for lipid metabolism and detoxification processes.Golgi Apparatus: Functions in modifying, sorting, and packaging of proteins for secretion or use within the cell.These organelles are crucial for the function and maintenance of eukaryotic cells, enabling the segregation of various biochemical processes.

Fats are specialized lipid molecules, and enzymes are specialized protein molecules. How do the functions of fats and enzymes differ?
A. Fats provide support for cells, while enzymes lower the pH of gastric fluids.
B. Fats are structural building materials, while enzymes are transportation molecules.
C. Fats are storage molecules, while enzymes are catalytic molecules.
D. Fats regulate body functions, while enzymes denature invasive bacteria.
Explain why.
Answer:
The correct answer is C. Fats are storage molecules, while enzymes are catalytic molecules.
Explanation:
Fats are primarily made up of carbon and hydrogen atoms which makes it hydrophobic in nature. Fat are macronutrient and they is stored on the liver which are utilized by the body in the scarcity of glucose and glycogen in the body. Fats can provide more calories that amino acids and glycogen after oxidation.
Enzymes are catalytic molecules that can regulate the reaction rate. Most of the enzymes increase the rate of the reaction and helps in completion of a metabolic process. Enzymes in the human body works more efficiently at 37°c.
Therefore fats are used for storage purpose and enzymes are used to catalyze a reaction. So the right answer is C.
What type of information is used to direct different polypeptides to fold into different shapes?
The folding of different polypeptides into unique shapes is directed by their amino acid sequence. The type and position of these amino acids determine the final three-dimensional structure of the protein, which in turn influences its function.
Explanation:The type of information that is used to direct different polypeptides to fold into different shapes is coded in the amino acid sequence of the polypeptide. This sequence influences how the polypeptide folds into its unique three-dimensional structure, which then determines its function. The shape of the polypeptide is extremely important as it determines the protein's activity and behavior in the cell. This folding process is influenced by the type of amino acids present and their relative positions in the sequence. For instance, hydrophobic amino acids usually tend to migrate towards the center of the protein, stabilizing the structure. Conversely, hydrophilic amino acids are found on the external surface of the protein, interacting with the surrounding water molecules in the cellular environment.

The type of information that is used to direct different polypeptides to fold into different shapes is the sequence of amino acids in the polypeptide.
The amino acid sequence determines the primary structure of the polypeptide, which is the linear sequence of amino acids.
The primary structure of the polypeptide determines its secondary structure, tertiary structure, and quaternary structure.
The secondary structure of a polypeptide is its three-dimensional structure as it folds back on itself. The secondary structure is stabilized by hydrogen bonds between the amino acids. The most common secondary structures are alpha helices and beta sheets.
The tertiary structure of a polypeptide is its three-dimensional structure in space. The tertiary structure is stabilized by a variety of interactions, including hydrogen bonds, ionic bonds, disulfide bonds, and hydrophobic interactions.
Here is an example of how the amino acid sequence influences the folding of a polypeptide:
The polypeptide hemoglobin contains a protein called globin. Globin is a globular protein, which means that it folds into a compact shape.
The globular shape of globin is essential for its function of carrying oxygen.
If the amino acid sequence of globin is changed, it can affect the way that the protein folds. For example, a mutation in the globin gene can cause a disease called sickle cell anemia.
In sickle cell anemia, the hemoglobin protein folds into a different shape, which makes it less effective at carrying oxygen.
The folding of polypeptides is a vital process for life. The shape of a polypeptide determines its function. By understanding how amino acid sequences influence the folding of polypeptides, scientists can better understand how proteins work and how to develop new treatments for diseases that are caused by protein misfolding.

Types of molecules that interact with each other during the reaction.
Further explanationEnzymes are composed of 2 parts:
a. Apoenzim parts are enzymes composed of proteins. Apoenzim is a type that dominates from all kinds of enzyme structures. Its unstable nature is easily changed when influenced by temperature and pH.
b. Parts of prosthetic groups are enzymes arranged on the basis of nonprotein. Based on the constituent, prosthetic there are two more parts, namely:
Coenzyme: Its job is to transfer chemicals from one enzyme to another.
Cofactor: Its job is to optimize the ptialin enzyme in breaking down complex sugar molecules.
Like all proteins, enzymes are made for very long, linear chains of amino acids that are folded to produce a three-dimensional product. Each unique amino acid produces a specific structural sequence, which is unique. Individual protein chains are sometimes grouped together to form complex proteins. Most enzymes can be denatured, stretched and inactivated by heating or chemical denaturation, disrupting the structure of the three dimension proteins. Depending on the enzyme, denaturation may not be changed or reversible.
Enzymes have 4 properties, namely:
1. an enzyme resembling a protein
2. Enzymes work back and forth
3. Enzymes work specifically
4. Enzymes are biocatalysts
