Question

1. Which of the following is false about photosynthesis?

A. ATP is the molecule used to store high energy electrons

B. the molecules used to build glucose are carbon dioxide and water

2. Which of the following is true when comparing eukaryotic and prokaryotic cells?

A. Some eukaryotic cells have membranes, others also have a cell wall. All prokaryotic cells have both a membrane and a cell wall.

B. It is possible to see eukaryotic cells without a microscope but not prokaryotic cells.

3. Which of the following is false concerning mutations?

A.they occur in both DNA and RNA

B. they can be repaired by DNA polymerase and additional repair enzymes in the cell

Answer 1

1) ATP is the molecule used to store high energy electrons

   In plants cells energy is stored in form glucose and starch in the plant cells which an be used later but not in form of ATP. Carbon dioxide and water combines to form glucose molecules which gets stored and used later by plant during growth and in formation of glucose energy is lost in form electrons.

2) It is possible to see eukaryotic cells without a microscope but not prokaryotic cells.

Both eukaryotic and prokaryotic cells have cell wand cell membrane around but the cell organelles of prokaryotic cells are not covered with any cell wall while the cell organelles of eukaryotic cell have distinct cell wall. Both cell of eukaryotic cell and prokaryotic cell can be seen without a microscope but viewing internal structures requires microscope.

3) they occur in both DNA and RNA

   Mutations are formation wrong genome sequences or copying of incorrect genome sequences during replication of DNA and these incorrect DNA sequences leads to formation of incorrect RNA sequences which eventually leads to production of incorrect proteins or non production of proteins due to wrong mRNA sequences produced by mutated DNA.
