Document Summary

Producers and consumers: plants and other autotrophs (self-feeders): Make their own organic matter from inorganic nutrients. Autotrophs are producers because ecosystems depends upon them for food: heterotrophs (other feeders): Include humans and other animals that cannot make organic molecules from inorganic ones. Heterotrophs are consumers because they eat plants or other animals. The metabolic pathway for cellular respiration: glucose + oxygen carbon dioxide + water + energy, c6h1206 + 6o2 6co2 + 6h20 + atp, a common fuel molecule for cellular respiration is glucose. Chemical cycling between photosynthesis and cellular respiration: the ingredients for photosynthesis are carbon dioxide and water. Co2 is obtained from the air by a plant"s leaves. H20 is obtained from the damp soil by a plant"s roots: chloroplasts in the cells of leaves: Use light energy to rearrange the atoms of co2 and h20 which produces: sugars (such as glucose, other organic molecules, oxygen, plant and animal cells perform cellular respiration, a chemical process that:

While Jill and Andre were studying for their Biology exam, Andre said, âAnimals perform cellular respiration and plants perform photosynthesis.â What about Andreâs statement should Jill have told him was incomplete?

Animals also perform photosynthesis.

Plants do not perform photosynthesis.

Animals do not perform cellular respiration.

Plants also perform cellular respiration.

Question 6

Select one answer.

One way to explain how cellular respiration and photosynthesis relate to each other is to say that:

Plant cells use the oxygen produced by respiration for photosynthesis.

The oxygen produced by photosynthesis, once released to the environment, is the oxygen able to be used as the electron acceptors for cellular respiration.

Cellular respiration is a series of reduction reactions while photosynthesis is a series of oxidation reactions.

The two processes are not related.

The use of oxygen by plants contributes to the greenhouse effect.

Microbiology Unit 2 Applied and Environmental Assignment Part 1:

Identify Nutritional requirements from Chapter 6 & 14 (and review from chapters 1 & 2)

1. Determine which of the 4 macromolecules require the following elements:

a. Carbon: carbohydrates___ lipids___ proteins___ nucleic acids___

b. Nitrogen: carbohydrates___ lipids___ proteins___ nucleic acids___

c. Sulfur: carbohydrates___ lipids___ proteins___ nucleic acids___

2. The essential elements mentioned above are cycled through cells and the earth in biogeochemical cycles like the carbon cycle, the nitrogen cycle, and the sulfur cycle. Select the correct answer and fill in the blanks to summarize these cycles:

a. Carbon dioxide is taken in from the atmosphere by [autotrophs/heterotrophs] and converted to glucose through carbon ________________. When heterotrophs eat autotrophs they catabolize glucose to make ATP through __________________ and waste carbon is released as ___________.

b. There is plenty of nitrogen available in the atmosphere but it is not accessible to organisms because it is in the form of Nitrogen gas (N2). N2 is fixed by [bacteria/plants/animals] and converted to ammonia (NH3.) NH3 can be used by [bacteria/plants/animals] to build their cells. Next, by consuming food with amino acids, [bacteria/plants/animals] can get access to nitrogen for their own cellular needs.

c. There is also a good quantity of sulfur in dirt, rocks, and the atmosphere. Sulfur cycles between H2S => S0 => SO4 => SH groups in Proteins => back to H2S. Using _________________ respiration, anoxygenic photosynthesis, and chemolithoautotrophy [bacteria/plants/animals] convert H2S and S0 to SO4 which is taken in by [bacteria/plants/animals] and used to build their cells. When [bacteria/plants/animals] eat plants they take in essential amino acids containing sulfur and recycle these to make their own proteins.

d. _________________ break down waste and dead organisms and recycle nutrients back into the cycles.

*The C and N are summarized here: https://youtu.be/2D7hZpIYlCA and https://youtu.be/leHy-Y_8nRs

3. Identify the main metabolic classifications:

A microbe that makes its own food by taking carbon from CO₂ in the atmosphere and its energy from sunlight
A microbe that makes its own food by taking carbon from CO₂ in the atmosphere and its energy from reduced inorganic chemicals
A microbe that eats other organisms to get organic carbon and energy
A microbe that uses organic carbon from others but energy from sunlight

Please help me with my microbiology assignment.
