Answer:
B.energy is consumed.
Explanation:
When ATP gain phosphate the energy is consumed(ADP+ Pi+ free energy→ ATP+ H2O). So in the formation of ATP energy is used and consumed and that energy is stored in the terminal phosphate bond.
This ATP act as the cellular form of energy and this energy is released when the terminal phosphate bond breaks and terminal phosphate is released from the ATP. This energy is used to perform the metabolic function required for cell survival and cell growth. Therefore energy is consumed in ATP formation.
<span>Watson and Crick determined the base pairing by using the new information to construct a new double-stranded helix model with the nitrogen bases paired A to T and C to G in the center. This base pairing immediately suggested to Crick that one side of the molecule could serve as a template to exactly replicate DNA sequences to pass on genetic information during cell reproduction. This second, successful model was unveiled in February 1951.</span>
Answer:
C. Nucleic Acids arranged in a double helix.
Explanation:
The structure of DNA is best described as a double helix. DNA has a sugar phosphate back and nucleotides connected by covalent bonds. Together, it looks like a twisted ladder which is also known the double helix.
Answer:
What can be deduced of cell that have densely packed mitochondria and the cristae are very closely together is that its function requires large amounts of energy.
Explanation:
Mitochondria are cellular organelles in charge of energy production. In these organelles occurs oxidative phosphorylation and electron transport chain, whose final product is ATP, an energy molecule.
A <u>cell with a large number of mitochondria, whose crests are very close together and tight, belongs to a tissue that has a lot of activity and its energy requirement is high</u>.
An example of cells with densely packed mitochondria are skeletal muscle and heart muscle.
