Which of the following best explains the function of an enzyme?
It helps reactants/ products get to the transition state and speed up reactions.
It increases the activation energy to speed up reactions.
It helps products get turned into reactants by lowering the activation energy.
It lowers the activation energy to destroy the transition state.
The sequence GUCAAACCUCCGG is an RNA sequence because it contains uracil (U) instead of thymine (T) like in DNA.
The likely function of lipase is to break down lipids (fats) into fatty acids and glycerol.
The RNA strand is 3’ UUAGCGA 5’. The other strand is made of the complementary base pairs: 5’ TAAGCTA 3’. The DNA strand 3’ TTAGCGA 5’ is the template strand.
The FALSE statement about nucleic acids is: RNA nucleotides bind to DNA during translation.
The proper sequence for the role of each of these in the cell is DNA, mRNA, tRNA, amino acid.
DNA replication requires the most nucleotides because it involves copying the entire DNA sequence in a cell.
The function of an enzyme is to help reactants/products reach the transition state and speed up reactions by lowering the activation energy.
