HESI Hint's...... ~(When attempting to understand cell respiration and photosynthesis, keep in mind that these processes are cyclical. In other words, the raw materials for one process are the products of the other process. The raw materials for cell respiration are glucose and oxygen, whereas the products of cell respiration are water, carbon dioxide, and ATP. Plants and other autotrophs will utilize the products of cell respiration in the process of photosynthesis. The products of photosynthesis (oxygen, glucose) become the raw materials of cell respiration.)......(The first stage of meiosis consists of four phases: prophase I, metaphase I, anaphase I, and telophase I and cytokinesis. The significant differences between meiosis and mitosis occur in prophase I. During this phase, nonsister chromatids of homologous chromosomes cross at numerous locations. Small sections of DNA are transferred between these chromosomes, resulting in increased genetic variation. The remaining three ph

Why is polarity the most important characteristic of water?

  1. The results of the polarity are hydrogen bonding, a high specific heat value, and its versatile solvent properties.
  2. The results of the polarity are covalent bonding, a low specific heat value, and its versatile solvent properties.
  3. The results of the polarity are ionic bonding, a high specific heat value, and its versatile solvent properties.
  4. The results of the polarity are hydrogen bonding, a low specific heat value, and its versatile solvent properties.

A cell from heart muscle would more than likely contain an unusually high proportion of:

  1. Lysosomes
  2. Mitochondria
  3. mRNA
  4. Ribosomes

B

5

Which part of cellular respiration produces the greatest amount of ATP?

  1. Electron transport chain
  2. Glycolysis
  3. Krebs cycle
  4. Fermentation

A

6

When plants do not receive enough water their photosynthetic rated drops. This is because:

  1. Water is a raw material for the light reactions in photosynthesis
  2. Carbon dioxide is not available
  3. Water provides the carbon atoms used to make sugar
  4. Not enough oxygen is produced to keep fermentation running.

A

7

Which of the following statements is true about the Krebs cycle and the Calvin cycle?

  1. Both result in a net production of ATP and NADH
  2. Both require a net input of ATP
  3. Both result in the release of oxygen
  4. Both use light to initiate the process.

A

8

Why is it important for cells to undergo mitosis?

  1. Mitosis allows for reproduction with male and female gametes
  2. Mitosis increases variation within the species
  3. Mitosis produces cells that are different from the parent cell
  4. Mitosis produces cells for growth and repair of body tissue

D
