What does the cytosol contain?
The cytosol contains a variety of molecules such as salts, organic molecules, enzymes, and other cellular components. It also serves as the site for many metabolic pathways within the cell. Additionally, it acts as a medium for transport of molecules within the cell.
What raw materials are needed for cellular respiration?
The primary raw materials needed for cellular respiration are glucose (sugar) and oxygen. Glucose is broken down in a series of metabolic pathways to produce energy in the form of adenosine triphosphate (ATP), while oxygen acts as the final electron acceptor in the electron transport chain to drive ATP production.
Why is Krebs cycle also called the final common pathway of the degradation of organic compounds?
The Krebs cycle is considered the final common pathway because it is the central metabolic pathway where glucose, fatty acids, and amino acids are ultimately broken down to produce energy in the form of ATP. It acts as a convergence point for different metabolic pathways, making it a central hub for energy production in the cell.
What kind of negative loops are used to regulate chemical pathways?
Negative feedback loops are commonly used to regulate chemical pathways. In these loops, the end product of a pathway acts as a signal to inhibit further production, helping to maintain homeostasis and prevent overaccumulation of certain substances. This regulation ensures that the pathway operates efficiently and does not waste resources.
What is the function of NADP?
NADP (nicotinamide adenine dinucleotide phosphate) serves as a coenzyme in many cellular processes, particularly in anabolic reactions such as photosynthesis and lipid biosynthesis. It acts as an electron carrier, accepting and donating electrons to drive these metabolic reactions.
What is G-3-P?
G3P is Glyceraldehyde 3-phosphate, a chemical compound that is found in organisms. G3P acts as a intermediate in metabolic pathways.

What is the role of ferredoxin?
Ferredoxin is a protein that plays a key role in electron transfer in various metabolic pathways, particularly in photosynthesis and cellular respiration. It acts as a carrier for electrons, shuttling them between different enzymes and complexes in these processes. Ferredoxin is essential for generating ATP, the energy currency of the cell.
How does NADP transfer electrons?
NADP transfers electrons by accepting them from other molecules in redox reactions, taking on two electrons and a proton to form NADPH. This process typically occurs in metabolic pathways such as photosynthesis and cellular respiration, where NADP acts as an electron carrier to facilitate energy production.
What is an anticonvulsive?
An anticonvulsant is an agent which acts against or attempts to prevent convulsions.
Which kind of metabolic poison would most directly interfere with glycolysis?
A metabolic poison that inhibits the enzyme phosphofructokinase, a key regulatory enzyme in glycolysis, would directly interfere with the glycolysis pathway. This enzyme is responsible for catalyzing an important regulatory step in glycolysis by converting fructose-6-phosphate to fructose-1,6-bisphosphate. Inhibiting this enzyme would disrupt the glycolytic pathway and hinder the breakdown of glucose to produce energy.
What type of biological agent the acts to destroy an organism?
Acid
Atropine acts as cholinergic agent by?
blockade of postsynaptic receptor
Polysaccharide that acts as a solidifying agent in microbiological media?
agar
In baked custard the egg acts as the thickening agent?
false
What means someone or something that acts or effects change?
Agent.
Is oxygen the oxidizing agent in combustion and the reducing agent in corrosion?
Yes, in combustion, oxygen acts as the oxidizing agent because it gains electrons from the fuel being burned. In corrosion, however, oxygen acts as the oxidizing agent as it accepts electrons from the metal, causing it to corrode or rust.
