Q: Answer the following question given this paragraph: Enzyme Compartmentalization In eukaryotic cells, molecules such as enzymes are usually compartmentalized into different organelles. This allows for yet another level of regulation of enzyme activity. Enzymes required only for certain cellular processes can be housed separately along with their substrates, allowing for more efficient chemical reactions. Examples of this sort of enzyme regulation based on location and proximity include the enzymes involved in the latter stages of cellular respiration, which take place exclusively in the mitochondria, and the enzymes involved in the digestion of cellular debris and foreign materials, located within lysosomes. Feedback Inhibition in Metabolic Pathways Molecules can regulate enzyme function in many ways. A major question remains, however: What are these molecules and where do they come from? Some are cofactors and coenzymes, ions, and organic molecules, as you've learned. What other molecules in the cell provide enzymatic regulation, such as allosteric modulation, and competitive and noncompetitive inhibition? The answer is that a wide variety of molecules can perform these roles. Some of these molecules include pharmaceutical and non-pharmaceutical drugs, toxins, and poisons from the environment. Perhaps the most relevant sources of enzyme regulatory molecules, with respect to cellular metabolism, are the products of the cellular metabolic reactions themselves. In a most efficient and elegant way, cells have evolved to use the products of their own reactions for feedback inhibition of enzyme activity. Feedback inhibition involves the use of a reaction product to regulate its own further production (Figure 6.21). The cell responds to the abundance of specific products by slowing down production during anabolic or catabolic reactions. Such reaction products may inhibit the enzymes that catalyzed their production through the mechanisms described above. Q: In eukaryotic cells, molecules such as enzymes are usually compartmentalized into different what? A:

OPTIONS:
- organisms
- atoms
- electrons
- organelles

A: organelles

input: OPTIONS:
- activation
- secretion
- metabolism
- diffusion Now, answer this question: Answer the following question given this paragraph: Absorptive protists absorb food molecules across their cell membranes. This occurs by diffusion. These protists are important decomposers. Q: Which process helps absorptive protists absorb food molecules across their cell membranes? A:
A:
output: diffusion

Answer the following question given this paragraph: In many species display behaviors, rather than actual physical attacks, are used to show aggression. This helps prevent injury and death. Male gorillas, for example, are more likely to put on a display of aggression than to attack another male. In fact, gorillas have a whole series of display behaviors that they use to show aggression. They beat on their chest, dash back and forth, and pound the ground with their hands. Q: How do the male gorillas show display behaviors? A:

OPTIONS:
- food gathering
- vocalization
- spontaneous mutation
- showing aggression

Answer: showing aggression

Problem: OPTIONS:
- Sedimentary
- asteroids
- metamorphic
- igneous
Q: Answer the following question given this paragraph: Igneous rocks are classified by composition and texture. The composition can be felsic, intermediate, mafic, or ultramafic. The composition depends on the minerals the rock includes. A felsic rock will contain felsic minerals. Q: Felsic, intermediate, mafic, and ultramafic are types of composition of what rock group? A:
Answer: igneous
