10th-III 3rd EV Biology Test

Draw the cell cycle with all the stages that it include

Explain how cancer is affected by viruses and how is a virus cycle related to it.

Explain the processes of the light dependent reaction and Calvin cycle, focusing on how the major molecules transform in both processes.

During which phase of meiosis do homologous chromosomes cross over?

• Prophase I

• Metaphase I

• Anaphase I

• Telophase I

What are the similarities between meiosis and mitosis?

• Both involve cell division

• Both consist of similar phases

• Both require DNA replication previous to cell division

• Both divide into haploid cells

What are the differences between meiosis and mitosis?

• Mitosis only occurs in somatic cells, while meiosis occurs in gametes.

• Mitosis involves 5 phases while meiosis involves 9

• In meiosis there is genetic diversity in the daughter cells, while in mitosis there is not.

• Mitosis divides into diploid cells, while meiosis into haploid cells

How many ATP are produced during electron transport or oxidative phosphorylation?

Explain the process of glycolysis.

Where does the citric acid cycle (Krebs cycle) take place in the cell?

What organisms can perform fermentation?

• Muscle cells of mammals

• Yeast in bread

• Bacteria in the gut of a cow

• Cyanobacteria in the ocean
