Which of the following is not true about GTP? ( guanosine 5 triphosphate)
It contains more than one high energy bond |
It contains one ester bond |
It contains three anhydride bonds |
It is a nucleotide |
GTP is a nucleotide with high energy and it takes part in the synthesis of RNA.
GTP has three phosphate anhydride linkeges or bonds in the structure.
Second option is not true because, there are three phosphate groups and these are esterified with sugar moeity

Guanosine triphosphate (GTP) is a nucleotide which consists of a 5-carbon sugar attached to guanine via a C-N bond between carbon {blank - i think the answer is c1} of ribose and {blank - i think the answer is n9} nitrogen of guanine, with a triphosphate group attached at carbon {blank} of ribose. please answer the places that are left blank in order to complete the sentence. I think I know the first two answers but I definitely dont know...
Which of the following statements is NOT true about acid anhydrides? A. Acid anhydrides are more reactive than esters but less reactive than acyl chlorides. B. An acid anhydride reacts with water to form an ester product. C. Acid anhydrides eliminate a carboxylate ion as a leaving group. D. An acid anhydride is considered to have a better leaving group (i.e. weaker base) than the leaving groups of esters, carboxylic acids, and amides. A B C D
Which of the statements about peptide bonds are true? D A tripeptide contains three amino acid residues. Peptide bonds are ester linkages. Peptide bond formation is a hydrolysis reaction. O Peptides are polymers of amino acids. Peptide bonds form from nucleophilic attack by an a-carboxyl carbon atom on an electron pair of an a-amino nitrogen atom of another amino acid.
Which of the following statements is true about the composition of lipoproteins? a HDL contains more cholesterol than LDL or VLDL. b LDL contains more cholesterol than HDL or VLDL c LDL contains more protein than HDL. d VLDL contains fewer triglycerides than HDL or LDL.
Indicate which of the following statements about the electromagnetic spectrum and IR spectroscopy are true and which are false. In any cases where the statement is false, explain how or why the statement is false. Infrared (IR) light is in the gamma ray part of the electromagnetic spectrum. Electromagnetic radiation is characterized by its mass and force. UV-Vis spectra are normally scanned in the 4000-600 cm-1 region. The fingerprint region on an IR spectrum is the easiest to interpret. Stronger...
Which of the following is not true about a water molecule? Select one: a. Contains polar covalent bonds because oxygen is more electronegative than hydrogen b. Has a bent shape c. Is made up of ions d. Has a permanent dipole, a separation of positive and negative charges Clear my choice
Problem 7. (ATP) In the human body, hydrolysis of ATP molecules (shown below) releases energy. During hydrolysis one of the three phosphate groups is broken off to give ADP, and a phosphate group, with the release of energy. Organisms make use of this energy to perform various biological functions. Adening High-energy bonds o-o-o -o -o 6 Ribose Phosphate Adenosine Adenosine monophosphate (AMP) Adenosine diphosphate (ADP) Adenosine triphosphate (ATP) A. An O - P bond in ATP is referred to as...
Which of the following about equilibrium constant of a reaction are true. It can change if the concentration of reactants and products are changed. It can be used to calculate the biochemical standard free energy change (Delta G degree). It can be used to calculate the actual free energy change (Delta G). It is the same as the mass action ratio (Q) when the reaction is in equilibrium. It is always a constant regardless of temperature change. Which of these...
Someone answered 3'OH, Ribonucleotide, Triphosphate and Ribonucleotide respectively, but one is incorrect, I dont know which one. Please help. The nucleotide shown here is called cordycepin triphosphate. It is a natural product of a fungus that is used in traditional medicines. P-P-P 5' Base он If cordycepin triphosphate is added to a cell-free transcription reaction, the nucleotide is added onto the growing RNA chain but then no more nucleotides can be added. Examine the structure of cordycepin and explain why...
