What makes up cell membranes and is used to create hormones

Hydrocarbon

Cholesterol

Starch

Glucose

The correct answer is: Cholesterol. Cholesterol is a type of lipid that is an important component of cell membranes. It helps maintain the fluidity and stability of the cell membrane. Additionally, cholesterol is also used by the body to synthesize hormones, such as estrogen and testosterone. Hydrocarbon, starch, and glucose are not directly involved in the structure of cell membranes or hormone synthesis.

All biomolecules have the following traits except

Hydrogen elements

A carbon backbone

Nitrogen elements

Covalent bonds

The correct answer is: Nitrogen elements.

While all biomolecules do contain hydrogen elements, a carbon backbone, and covalent bonds, not all biomolecules contain nitrogen elements. Nitrogen is commonly found in biomolecules such as proteins and nucleic acids, but it is not present in other biomolecules like carbohydrates and lipids.

What enzyme breaks down Starch in your saliva

Trypsin

Amylase

Lipase

Pepsin

The correct answer is: Amylase. Amylase is the enzyme that breaks down starch in your saliva. It is produced by the salivary glands and begins the process of breaking down complex carbohydrates into smaller sugar molecules. Trypsin, lipase, and pepsin are enzymes involved in the digestion of proteins and fats, respectively, but they do not break down starch.

Which soil based compounds do plants use to create amino acids from glucose

Carbon

Hydrogen

Fluoride

Nitrogen

The correct answer is: Nitrogen. Plants use nitrogen from the soil to create amino acids from glucose. Nitrogen is a vital nutrient for plants and is a fundamental component of amino acids, which are the building blocks of proteins. Carbon, hydrogen, and fluoride are also important elements, but they are not directly involved in the process of creating amino acids from glucose.

What are the building blocks of proteins

Amino acids

Starch

Sugars

Fatty acids

The correct answer is: Amino acids. Amino acids are the building blocks of proteins. Proteins are composed of long chains of amino acids linked together by peptide bonds. Starch, sugars, and fatty acids are not the building blocks of proteins. Starch and sugars are carbohydrates, while fatty acids are the building blocks of lipids.

The correct answer is cholesterol.

To determine the substances that make up cell membranes and are used to create hormones, we need to understand the components of cell membranes and hormone synthesis.

Cell membranes are primarily composed of a double layer of phospholipids. These phospholipids consist of a hydrophilic (water-loving) head and a hydrophobic (water-repelling) tail. This arrangement creates a barrier between the aqueous environment inside and outside the cell.

While hydrocarbons are a large class of organic compounds that can be found in cell membranes, they are not the specific component responsible for hormone synthesis or major structural elements of cell membranes.

Starch and glucose are types of carbohydrates, which are not major components of cell membranes. They primarily serve as an energy source for cells rather than being used for hormone synthesis or membrane structure.

On the other hand, cholesterol is a lipid molecule that is both a component of cell membranes and plays a crucial role in hormone synthesis. Cholesterol contributes to the fluidity and stability of cell membranes. It is also used by the body to produce various hormones, including adrenal hormones such as cortisol and sex hormones like estrogen and testosterone. Cholesterol serves as a precursor for these hormones, meaning it is transformed into these hormone molecules through various enzymatic reactions.

In summary, while hydrocarbons, starch, and glucose have roles within cells, cholesterol is the specific substance that is a major component of cell membranes and is used in hormone synthesis.
