Which is NOT a major type of carbohydrate?

A. Lowering the potential energy of the products

B. Separating inhibitors from products

C. Forming a complex with the products

D. Lowering the activation energy of the reaction

Enzymes act as catalysts for biochemical reactions. A catalyst is not consumed in a reaction, but rather lowers the activation energy for that reaction. The potential energy of the substrate and the product remain the same, but the activation energy-the energy needed to make the reaction progress can be lowered with the help of an enzyme.

A. Monosaccharides

B. Disaccharides

C. Pentasaccharides

D. Polysaccharides

There are four major types of carbohydrates: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides (mono- means one) are made up of one sugar molecule, while disaccharides (di- means two) are made up of two sugar molecules. Oligosaccharides (oligo- means few) are usually less than a dozen sugar molecules, while polysaccharides (poly-means many) are usually more than a dozen sugar molecules.

Pentasaccharides are not a type of carbohydrate.

A. 1s

B. 3s

C. 4p

D. 6s

Of these orbitals, the last to fill is 6s.

Orbitals fill in the following order: 1s, 25, 2p. 35, 3p, 4s, 3d, 4p, 55, 4d, 5p. 6s, 4f, 5d, 6p. 7s, 5f, 6d, and 7p. The number is the orbital number, and the letter is the sublevel identification. Sublevels has one orbital and can hold a maximum of two electrons. Sublevel p has three orbitals and can hold a maximum of six electrons. Sublevel d has five orbitals and can hold a maximum of 10 electrons, Sublevel f has seven orbitals and can hold a maximum of 14 electrons.

A. They change shape when they bind their substrates.

B. They can catalyze reactions in both forward and reverse directions.

C. Their activity is sensitive to changes in temperature.

D. They are always active on more than one kind of substrate.

Enzymes are substrate-specific. Most enzymes catalyze only one biochemical reaction. Their active sites are specific for a certain type of substrate and do not bind to other substrates and catalyze other reactions.

A. Fibrous

B. Membrane

C. Globular

D. Unsaturated

There are three types of proteins: fibrous, membrane, and globular. Fibrous or structural proteins consist of collagen, elastin, and keratin. Membrane proteins are interactive and anchored to a membrane. Globular proteins consist of functional proteins like enzymes, hemoglobin, and insulin.

Therefore unsaturated is the correct answer.

A. A better understanding of the physical world

B. The ability to predict possible outcomes affected by actions

C. The ability to prevent earthquakes and other natural disasters

D. The creation of various substances and technologies that enhance our world

Scientists make observations, gather data, and complete research over many years in order to compile knowledge that will provide insight into future disasters, such as earthquakes, storms, and global warming. Although science can be used to predict earthquakes and other natural disasters, there is currently no way of preventing them from occurring.

A. An organelle is a specialized structure in a cell, such as a ribosome.

B. An organ is made up of similar tissues that perform the same function.

C. Organ systems are two or more organs performing similar functions.

D. A tissue contains a single cell type that works to perform a specific function.

A tissue contains a variety of cell types that work in conjunction to perform similar functions.

The cells are similar in structure despite being located throughout the body. There are four types of tissues in the human body: connective, epithelial, muscle, and nervous system tissues.

A. Hair

B. Nails

C. Skin

D. Iris

While melanin can be found in nails, it is not produced there. Melanin is the pigment that provides color to skin, hair, and eyes. Although the specific coloring of one's skin, hair, and eyes are genetically determined. environmental factors such as sun exposure can increase melanin production in the skin to help protect it from damage.

A. Golgi bodies

B. Rough endoplasmic reticulum

C. Secretory vesicles

D. Endocytic vesicles

Endocytosis is a process by which cells absorb larger molecules or even tiny organisms, such as bacteria, that would not be able to pass through the plasma membrane. Endocytic vesicles containing molecules from the extracellular environment often undergo further processing once they enter the cell.

A. Make proteins

B. Waste removal

C. Transport

D. Storage

A ribosome is a structure of eukaryotic cells that makes proteins.
