Biochemical Molecules and Properties Quiz

Carbohydrates serve as the primary source of energy in living organisms through their conversion into glucose, which undergoes cellular respiration.

During glycolysis, glucose is metabolized into pyruvate, producing ATP and serving as a crucial step in cellular respiration.

Uracil is a nitrogenous base present in RNA, replacing thymine found in DNA during the process of transcription.

Hemoglobin's primary function is to bind and transport oxygen in the bloodstream, facilitating oxygen delivery to tissues and organs.

Cellulose, a structural polysaccharide, is a major component of plant cell walls, providing strength and rigidity.

Enzymes act as catalysts, accelerating biochemical reactions by lowering the activation energy required for the reactions to occur.

Saturated fatty acids typically have a straight structure and tend to be solid at room temperature due to close packing of molecules.

Ribosomes are cellular structures responsible for protein synthesis, facilitating the assembly of amino acids into polypeptide chains.

Vitamin C is a water-soluble vitamin, essential for various biological processes, including collagen synthesis and antioxidant defense.

The Golgi apparatus processes, modifies, and packages proteins, preparing them for secretion or incorporation into cellular membranes.

The primary structure of a protein is determined by the specific sequence of amino acids in its polypeptide chain.

Nucleic acids, such as DNA and RNA, are primarily involved in the storage and transmission of genetic information, not in energy storage.

ATP (adenosine triphosphate) serves as a universal energy currency in cells, storing and transferring energy for various cellular processes.

The endoplasmic reticulum is involved in the synthesis, modification, and packaging of proteins for secretion or transport within the cell.

Coenzymes assist enzymes by facilitating the transfer of electrons during enzymatic reactions, playing a crucial role in metabolic processes.
