Question

The Core 1. Energy can be divided up into potential energy and kinetic energy. Label each of the items below as either "potential" or "kinetic" energy. Heat 2. What is the ultimate goal of cellular respiration? ATP Food Muscle contraction 3. Please fill in the following blanks with the terms: lactic acid fermentation, alcohol fermentation, aerobic respiration, oxygen, ATP, sugars, water, CO2 When oxygen is present, cells will use amount of respiration to produce the maximum for doing work in the cell. For this process, the inputs are and while the products are , and However, when oxygen is depleted or absent, cells can switch to less efficient reactions such as - or 4. Please describe the general universal characteristics of prokaryotes (as opposed to eukaryotes). 5. To what domain and kingdom do yeast belong? Do you think they are they more similar to humans or bacteria? Why?

Explanation / Answer

1) Heat - Kinetic energy

ATP - Potential energy

Food - Potential energy

Muscle contraction - Kinetic energy

2) Cellular Respiration is needed to harvest energy from glucose and other energy-rich carbon- based molecules and use it to make ATP, which is the universal energy molecule.

3) Aerobic respiration

ATP

Oxygen and Sugars

Water, CO2 and ATP

Lactic acid fermentation or alcohol fermentation

4) Prokaryotes lack an organized nucleus and other membrane-bound organelles.

Prokaryotic DNA is found in a central part of the cell called the nucleoid.

The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration.

5) Yeast:

Domain: Eukaryote

Kingdom: Fungus

Yeast cells are more similar to humans. The cellular biology of yeast and humans - how they grow and divide, age, and metabolize food is remarkably similar. Yeast and humans share genes that carry out similar functions.
