(a) Interpretation: If life were to exist elsewhere in the universe, it would require some process like photosynthesis. Concept introduction: The plants use the sun’s light energy to convert water and carbon dioxide to form energy-rich glucose molecules by the process of photosynthesis. Photosynthesis occurs in the chloroplasts of plants. Animals being heterotrophic consume plants or other animals for energy requirements.

Interpretation Introduction

(a)

Interpretation:

If life were to exist elsewhere in the universe, it would require some process like photosynthesis.

Concept introduction:

The plants use the sun’s light energy to convert water and carbon dioxide to form energy-rich glucose molecules by the process of photosynthesis. Photosynthesis occurs in the chloroplasts of plants. Animals being heterotrophic consume plants or other animals for energy requirements.

Interpretation Introduction

(b)

Interpretation:

If the Starship Enterprise were to land on a distant planet and find no measurable oxygen in the atmosphere, could the crew conclude that photosynthesis is taking place or not.

Concept introduction:

Water acts as the electron donorin photosynthesis to produce glucose and oxygen. The absence of water hampers the process.

9) Below, there is a representation of an SDS-PAGE gel. Assuming the samples in the MW standard have masses of: 66 kDa, 45 kDa, 36 kDa, 29 kDa, 24 kDa, 20.1 kDa, and 14.2 kDa, a) Figure 4: indicate where each of the measurements were taken and label as in II.6. figure 2 above. b) As in II.7. Table 1 above create Table 2 using the data below. Determine the r.f. values for the MW standards, plot the relative mobility versus the log of the mass for the standards, and use the best fit straight line to determine the molecular weights of the proteins in the whey, peak 1, and peak 2 lanes.
