How do cells regulate synthesis to conserve energy?
Cells regulate synthesis by controlling the activation of enzymes involved in metabolic pathways. This is done through feedback inhibition, where the end product of a pathway inhibits the enzyme responsible for its synthesis. By regulating when and how much of a certain product is produced, cells can conserve energy by only making what is necessary for their immediate needs.
In living cells chemical processes such as synthesis require the action of?
Biological catalysts
Where cycloheximide inhibit protein synthesis?
Cycloheximide inhibits protein synthesis in eukaryotic cells by blocking translocation on the ribosome. It binds to the 60S subunit of the ribosome and prevents the elongation of the polypeptide chain during translation. This stops the synthesis of new proteins, leading to the disruption of cellular processes that rely on protein production.
What of the functions in human cells involve chemical reactions?
Many functions in human cells involve chemical reactions, including metabolism, protein synthesis, DNA replication, and cell signaling. These chemical reactions are vital for maintaining cellular homeostasis, producing energy, synthesizing essential molecules, and carrying out various biological processes.
Is chemical reactions needed to build new cells?
Yes, chemical reactions are essential for the creation of new cells. These reactions involve the synthesis of new molecules such as proteins and nucleic acids, which are building blocks of cells. Without these chemical processes, cells would not be able to grow and reproduce.

A drug is introduced into cells that affects the mechanics of the electron transport chain. Specifically, this drug completely inhibits the flow of electrons through the electron transport chain and also completely halts the synthesis of ATP?
Cyanide, which inhibits the activity of cytochrome C oxidase

What drug inhibits the growth of infectious microorganisms?
Antibiotics inhibit the growth of infectious microorganisms by targeting specific components of bacterial cells, such as cell wall synthesis or protein production. Different antibiotics work in different ways to disrupt the processes necessary for bacterial growth and replication.
What happens to muscle cells in aging?
Muscle cells can decrease in size and number as we age, a condition known as sarcopenia. This can lead to a loss of muscle strength and functionality. Additionally, there may be a reduction in muscle mass due to changes in protein synthesis and increased inflammation.
How do prokaryotic cells use strategies to isolate and organize their chemical reactions?
Prokaryotic cells use compartmentalization and specialized structures to isolate and organize their chemical reactions. This helps them efficiently carry out processes like metabolism and protein synthesis.
Why do cells not continue to divide once frozen?
because the state inhibits it.
Why bacterial cell are sensitive to streptomycin and chloramphenicol antibiotic?
Bacterial cells are sensitive to streptomycin because it targets the bacterial ribosomes, interfering with protein synthesis. Chloramphenicol, on the other hand, inhibits protein synthesis by binding to the bacterial ribosomes and preventing the aminoacyl-tRNA from reaching the ribosome. These antibiotics disrupt essential bacterial processes, leading to cell death.
Is growing hair a chemical or physical change?
Growing hair is a biological process that involves physical changes. Cells in hair follicles divide and differentiate to produce new cells, which then form hair strands. This process does not involve a chemical reaction that alters the chemical composition of the hair.
