- 1What is a nucleotide?The monomer for which nucleic acids are made.
- 2What is the structure of a nucleotide?Pentose sugar
Nitrogenous base
Phosphate group
All nucleotides contain C, H, O, N and P - 3What is the structure of DNA nucleotides?Deoxyribose (sugar)
Phosphate group
Four possible bases - adenine (A), thymine (T), cytosine (C) and guanine (G) - 4What is the structure of RNA nucleotides?Ribose (sugar)
Phosphate group
Four possible bases - adenine (A), uracil (U), cytosine (C) and guanine (G) - 5What are purines?Adenine and guanine
2 carbon-nitrogen rings joined together
- 6What are the two types of bases present in DNA and RNA nucleotides?Purines and pyrimidines
- 7What are pyrimidines?Cytosine, thymine and uracil
1 carbon-nitrogen ring
- 8What does ATP stand for?Adenosine triphosphate
- 9What is the structure of ATP?Ribose
Adenine
3 phosphate groups
- 10What is the process in which ATP is broken down into ADP and inorganic phosphate (Pi)?Hydrolysis
- 11Complete the sentences: Plant and animal cells release ______ from glucose through ___________. A cell cannot get its energy directly from glucose. So, in respiration, the energy released from ________ is used to make _____ and then molecules of ATP provide energy for ___________ __________ in the cellPlant and animal cells release ENERGY from glucose through RESPIRATION. A cell cannot get its energy directly from glucose. So, in respiration, the energy released from GLUCOSE is used to make ATP and then molecules of ATP provide energy for CHEMICAL REACTIONS in the cell.
- 12Where is energy stored in ATP?In the phosphate bond
When this energy is needed by a cell, ATP is broken down into ADP and Pi
