Dehydration synthesis and hydrolysis are accomplished in cells by?
Dehydration synthesis is achieved by removing a water molecule to build new molecules, while hydrolysis breaks down molecules by adding a water molecule. In cells, dehydration synthesis is carried out by enzymes that catalyze the formation of new chemical bonds, while hydrolysis is facilitated by enzymes that break down complex molecules into simpler components. Both processes play crucial roles in cellular metabolism and the synthesis and breakdown of biological molecules.
What part do ATP and ADP play in the synthesis of organic molecules?
ATP contains a high energy bond which is used to transfer energy inside cells. This energy is then used to form the bonds that build other organic molecules. Once ATP has been used, it reverts to ADP which lacks the high energy bond of ATP. Cellular respiration releases energy from sugars and fats in order to convert ADP back into ATP.
What is the one job in whack most RNA molecules are involved?
RNA molecules are most involved in protein synthesis, specifically in the process of translation where messenger RNA (mRNA) is decoded by ribosomes to produce proteins. RNA molecules such as transfer RNA (tRNA) and ribosomal RNA (rRNA) play key roles in this process by carrying amino acids and forming the ribosome structure, respectively.
What is the role of molecules such as nadph and nadh and fadh2 in metabolic processes?
NADPH, NADH, and FADH2 are molecules that carry energy in the form of electrons during metabolic processes. They play crucial roles in processes like glycolysis, the citric acid cycle, and oxidative phosphorylation to generate ATP, the energy currency of the cell. NADPH is particularly important for anabolic reactions like lipid and nucleic acid synthesis.
How does mitochondria contribute to the creation of proteins within the cell?
Mitochondria play a crucial role in protein synthesis by providing the energy needed for the process. They generate ATP, which is the energy currency of the cell, through a process called cellular respiration. This energy is used by ribosomes, the cellular machinery responsible for protein synthesis, to assemble amino acids into proteins. In summary, mitochondria contribute to the creation of proteins within the cell by producing the energy required for protein synthesis to occur.
Is synthesis of large molecules from smaller molecules.?
Yes, the synthesis of large molecules from smaller molecules is known as polymerization or macromolecule synthesis. This process involves the chemical bonding of smaller units, called monomers, to form larger, more complex structures such as proteins, nucleic acids, and synthetic polymers. These large molecules play critical roles in biological systems and various applications in materials science.

What types of enzymes build molecules?
Enzymes that build molecules are primarily classified as anabolic enzymes. These include ligases, which join two molecules together, and synthases, which catalyze the synthesis of larger molecules from smaller units. Other examples include polymerases, which synthesize polymers like DNA and RNA, and peptidyl transferase, which forms peptide bonds in protein synthesis. These enzymes play crucial roles in cellular processes such as growth, repair, and energy storage.
What are large complex molecules formed by joining together many smaller molecules include?
Large complex molecules formed by joining together many smaller molecules include proteins, nucleic acids (DNA and RNA), polysaccharides, and lipids. These macromolecules play crucial roles in biological functions such as cell structure, energy storage, and genetic information storage.
What does RNA synthesis produce?
RNA synthesis produces RNA molecules using a DNA template as a guide. This process, known as transcription, involves the synthesis of mRNA, tRNA, and rRNA, which play essential roles in protein synthesis and other cellular processes.
What is the definition of complex organic molecules?
Complex organic molecules are large molecules made up of carbon atoms bonded together with other elements such as hydrogen, oxygen, nitrogen, and sulfur. These molecules are essential for life and play important roles in biological processes.
Which three molecules are involved in synthesis?
The three key molecules involved in synthesis are amino acids, nucleotides, and monosaccharides. Amino acids are the building blocks of proteins, nucleotides are the monomers of nucleic acids (like DNA and RNA), and monosaccharides are the simplest carbohydrates that can combine to form polysaccharides. Together, these molecules play crucial roles in the biological synthesis of macromolecules, which are essential for cellular structure and function.
What is the process of breaking down complex food molecules into simpler food molecules?
The process of breaking down complex food molecules into simpler food molecules is called digestion. It begins in the mouth with the mechanical and chemical breakdown of food, continues in the stomach where more chemical digestion occurs, and is completed in the small intestine where nutrients are absorbed into the bloodstream. Enzymes play a key role in this process by breaking down larger molecules into smaller ones that the body can use for energy and growth.
What is the work of protein?
Proteins are large, complex molecules that play many critical roles in the body.
What is complex lipids?
Complex lipids are a type of biomolecule that consist of a lipid and other molecules like proteins, sugars, or phosphate groups. They play important roles in cell membranes, energy storage, and cell signaling. Examples include phospholipids, glycolipids, and lipoproteins.
What organelle of a cell is responsible for synthesis of new molecules?
The organelle responsible for the synthesis of new molecules in a cell is the ribosome. Ribosomes are the sites of protein synthesis, where they translate messenger RNA (mRNA) into polypeptide chains, which then fold into functional proteins. Additionally, the endoplasmic reticulum (specifically the rough ER) is involved in the synthesis and processing of proteins, while the smooth ER is responsible for lipid synthesis. Together, these organelles play key roles in the production of various biomolecules.
