An apoenzyme that loses its coenzyme or cofactor will be non-functional.
|
Apoenzymes- It is an inactive enzyme which activates after binding to an organic or inorganic cofactors to form holoenzymes (active form of apoenzymes). Without its cofactor or coenzyme, apoenzyme will be non-functional.
Therefore, the given statement is true
An apoenzyme that loses its coenzyme or cofactor will be non-functional. True False
QUESTION 4 Which of the following statements is false? a. A cofactor may be an exogenous small molecule necessary for enzymatic function. b. A holoenzyme lacks its cofactor and/or coenzyme. c. A coenzyme is typically a vitamin-derived component. d. A ligase typically uses ATP cleavage to form bonds. e. An apoenzyme is typically catalytically inactive.
Approximately 4% of cellular enzymes use coenzyme A. Understanding the role of this cofactor is critical to understanding many metabolic processes, such as glucose oxidation and fatty acid oxidation. A) What is coenyme A and what are its important structural features? B) What is its role (or the role of acetyl-CoA) in metabolism? C) What advantages does this cofactor impart?

Let A be an n×n matrix. Mark each statement as true or false. Justify each answer. a. An n×n determinant is defined by determinants of (n−1)×(n−1) submatrices. b. The (i,j)-cofactor of a matrix A is the matrix obtained by deleting from A its I’th row and j’th column. a. Choose the correct answer below. A. The statement is false. Although determinants of (n−1)×(n−1)submatrices can be used to find n×n determinants,they are not involved in the definition of n×n determinants. B....
