What is the stage of cell division that is responsible for cell growth and production of new organelles and enzymes?
The interphase stage of the cell cycle is responsible for cell growth and the production of new organelles and enzymes. During this stage, the cell prepares for division by replicating its DNA and synthesizing proteins necessary for cell division.
What cell have synthesizing polypeptides?
Ribosomes are the cellular structures responsible for synthesizing polypeptides. They can be found either free-floating in the cytoplasm or attached to the endoplasmic reticulum, forming rough ER. During protein synthesis, ribosomes translate messenger RNA (mRNA) into a specific sequence of amino acids, ultimately forming polypeptides. This process is essential for producing proteins necessary for various cellular functions.
What cellular organelle is responsible for synthesizing the most ATP?
The mitochondrion is the cellular organelle responsible for synthesizing the most ATP. It generates ATP through the process of oxidative phosphorylation during cellular respiration, utilizing the electron transport chain and chemiosmosis. This organelle is often referred to as the "powerhouse of the cell" due to its critical role in energy production.
Are organelles made during growth phase 2?
No, organelles are not made during growth phase 2 (G2) of the cell cycle. This phase is mainly focused on preparing the cell for division by synthesizing proteins and organelles are generally not synthesized during this time.
Do cells have the capability of synthesizing water during metabolism?
Many metabolic processes involve condensation reactions, a type of reaction forming new bonds that produces water as a "waste product".

Does RNA polymerase require helicase for its function?
No, RNA polymerase does not require helicase for its function. RNA polymerase is responsible for synthesizing RNA from a DNA template, while helicase is an enzyme that unwinds the DNA double helix during processes like DNA replication and transcription.
Do ribosomes translate mRNA into proteins during the process of protein synthesis?
Yes, ribosomes are responsible for translating mRNA into proteins during the process of protein synthesis.

Are responsible for the transport of substances down a concentration gradient during facilitated diffusion.?
Carrier proteins
When you are asleep what is the energy in your body used for?
While you sleep, your body uses energy for several vital functions, including repairing and regenerating tissues, synthesizing proteins, and releasing hormones. Sleep is also crucial for brain activity, as it processes and consolidates memories, regulates emotions, and clears metabolic waste. Additionally, energy is expended for maintaining basic physiological processes, such as breathing and circulation, even during rest.
What stage of the cell cycle is the nucleolus always visible?
The nucleolus is always visible during interphase, particularly during the G1, S, and G2 phases of the cell cycle. This is when the cell is actively growing and synthesizing proteins.
Do cells have the capability of synthesizing water during metabolism?
Many metabolic processes involve condensation reactions, a type of reaction forming new bonds that produces water as a "waste product".
What might be occurring on a molecular level during the rest periods?
During rest periods, molecular processes such as DNA repair, protein synthesis, and energy storage may be occurring. Cells might be replenishing energy stores, repairing damaged molecules, and synthesizing new proteins to support cellular functions. This allows the body to recover and prepare for the next activity.
What attaches to the mRNA strand as translation begins?
After the two ribosomal subunits attach to a strand of mRNA, a tRNA molecule with the amino acid methionine attaches to the start codon, AUG.
