Biology Mid Term- 4

  1. Cellular respiration occurs in the mitochondria of the cell.
  2. Photosynthesis occurs in the chloroplast of the cell.
  3. List the two major reactions that occur during photosynthesis: light dependent and light independent
  4. Explain the difference between autotrophs and heterotrophs.

Autotrophs produce their own food, heterotrophs must consume food

  1. What organisms are capable of photosynthesis?

eukaryotic and prokaryotic

  1. The light reactions occur in the thylakoid membrane, while the Calvin Cycle occurs in the stroma.
  2. Plants reflect green light and absorb blue and red light best.
  3. Explain the difference between anabolic and catabolic reactions.

Catabolic- breaks down compounds Anabolic- builds them back up

  1. Anabolic reactions can also be called endergonic, which means energy-absorbing. Catabolic reactions can also be called exergonic, which means energy-releasing.
  2. Describe the structure of Adenosine Triphosphate (ATP).

Double helix (looks like two ropes continuously wrapped around each other)

  1. Which part of the ATP molecule gives it the ability to do work?

Phosphate tail

  1. Electron transport chain perform both photosynthesis and cellular respiration, while light reactions only perform cellular respiration.
  2. Copy and paste a labeled diagram of a mitochondrion below:

 

  1. Approximately 38 ATP are produced during cellular respiration.
  2. In the equations for photosynthesis and cellular respiration(shown below), label all of the reactants and products with their names below each equation:

6CO2 + 6H20 → C6H12O6 + 6O2

photosynthesis

C6H12O6 + 6O2 → 6CO2 + 6H2O
