What else can I help you with?
I phosphate a base?
Phosphorylation is a post-translational modification where a phosphate group is added to a protein or other organic molecule, typically leading to changes in its structure or function. The addition of a phosphate group to a base (such as in DNA or RNA) is less common and can occur in specific biological processes, like during DNA replication or repair. It can affect the stability or reactivity of the base, influencing its role in genetic processes.
Describe the first reaction in glycolysis Is this reaction catalyzed by an enzyme?
The first reaction in glycolysis is the phosphorylation of glucose to glucose-6-phosphate by the enzyme hexokinase. This reaction involves the transfer of a phosphate group from ATP to glucose, requiring energy for activation.
What happens when you add sodium phosphate to calcium nitrate?
A chemical reaction will occur, resulting in the formation of insoluble calcium phosphate (a white solid) and sodium nitrate dissolved in the solution. This reaction is a double displacement reaction where the ions switch partners.
Does phosphoric acid react with copper?
Yes, phosphoric acid can react with copper to form copper phosphate and hydrogen gas. This reaction can occur more readily in concentrated solutions of phosphoric acid.
Muscle tissue that is lost is replaced by noncontractile?
connective tissue, leading to decreased muscle function and strength. This process is known as muscle atrophy, and it can occur due to factors such as disuse, aging, or certain medical conditions. Physical therapy and exercise can help prevent or slow down muscle atrophy.
Where does the pentose phosphate pathway occur?
The pentose phosphate pathway occurs in the cytoplasm of cells. It is a metabolic pathway that generates NADPH and produces ribose-5-phosphate, which is important for nucleotide synthesis and other cellular processes.
What metabolic pathway is anabolic?
anabolic pathway is one that the products are more complicated than reactants. they usually need energy(ΔG>0) anabolic pathways are enzymatic and occur in living organism cells and uses energy to construct components of cells such as protein and nucleic acid.
Which event occurs during phosphate?
Phosphate is not a period of time during which an event can occur.
What are the steps of Coagulation pathway?
Blood coagulation can occur either through an intrinsic or extrinsic pathway. The first step in either pathway begins with the production of Factor X,which marks the common pathway of coagulation.
What are 3 ways in which ATP is regenerated during skeletal muscle contraction?
During a skeletal muscle contraction, the three ways in which ATP is generated are through direct phosphorylation, anaerobic pathway and aerobic respiration. In direct phosphorylation, ADP is phosphorylated by creatine phosphate; in anaerobic pathway, glycolysis and lactic acid formation occur; and in aerobic respiration, 95% of ATP is produced.
Where does glyoxylate pathway occur?
The glyoxylate pathway occurs in the peroxisomes of eukaryotic cells and in the cytoplasm of prokaryotic cells. It is a metabolic pathway that allows some organisms to convert fatty acids into carbohydrates for energy production.
Does fat metabolism occur before the creatine phosphate reserves are depleted?
no
Where does emp pathway occur?
cytoplasmic matrix of procaryotes and eucaryotes with presence or absence of oxygen
Why does cystitis occur commonly in women than in men?
Female urethral pathway is shorter
Where does EDP pathway occur?
EDP pathway occurs in cytoplasmic matrix of soil microbes like pseudomonas , rhizobium , acetobacter , agrobacterium and gram negative bacteria. a gram positive bacteria , enterococcus faecalis also uses this pathway.
When does excision occur?
When you cut a tissue with a knife.
Is a malignant tumor that occur in epithelial tissue?
A carcinoma is a malignant tumor that occurs in epithelial tissue.
