Plants (autotrophs) can convert sunlight energy into chemical energy, but animals
(heterotrophs) cannot. Plants and animals can both convert redox energy into chemical energy.
- correct answer ✔✔1,7,11,6
DNA encodes the genetic information of cells. Based on your understanding of the Central
Dogma of Biochemistry, choose the most correct underlined words below and record your
answers. Genetic inheritance requires that DNA be copied by a process called replication/
translation. Gene segments of RNA / DNAare functional units defined by the nucleic acid
products they produce. RNA molecules that encode proteins are called ribosomal /
messengerRNA and are used as templates for transcription / translation. Proteins are the
workhorses of living cells and function as metabolic enzymes/ cofactors, as well as signaling
molecules such as receptors - correct answer ✔✔replication, dna, messenger, translation,
enzymes
Calculate the DG value at 25 °C for the reaction converting fumarate to malate, given the
standard change in free energy of this reaction is -3.8 kJ/mol, the concentration of fumarate is
0.010 M, and concentration of malate is 0.02 mM. - correct answer ✔✔-19.2 kj/mol
