Answer the following question given this paragraph: Many biochemical processes occur through sequences of reactions called pathways. The total energy released by many of these pathways is much more than the energy a cell could handle if it were all released in a single step. For example, the combustion of glucose in a single step would release enough energy to kill a cell. By using a series of smaller steps that release less energy per reaction, however, the cell can extract the maximum energy from glucose without being destroyed. Referring to Equation 5.30, calculate how many grams of glucose would need to be metabolized to raise the temperature of a liver cell from an average body 3. Q: Some biochemical processes happen via sequences of reactions which are called what? Choices: - synthesis - mutations - metabolism - pathways A:
pathways
Answer the following question given this paragraph: 2.3 Chemical Reactions Chemical reactions, in which chemical bonds are broken and formed, require an initial investment of energy. Kinetic energy, the energy of matter in motion, fuels the collisions of atoms, ions, and molecules that are necessary if their old bonds are to break and new ones to form. All molecules store potential energy, which is released when their bonds are broken. Four forms of energy essential to human functioning are: chemical energy, which is stored and released as chemical bonds are formed and broken; mechanical energy, which directly powers physical activity; radiant energy, emitted as waves such as in sunlight; and electrical energy, the power of moving electrons. Chemical reactions begin with reactants and end with products. Synthesis reactions bond reactants together, a process that requires energy, whereas decomposition reactions break the bonds within a reactant and thereby release energy. In exchange reactions, bonds are both broken and formed, and energy is exchanged. The rate at which chemical reactions occur is influenced by several properties of the reactants: temperature, concentration and pressure, and the presence or absence of a catalyst. An enzyme is a catalytic protein that speeds up chemical reactions in the human body. Q: What term is used to describe the energy of matter in motion? Choices: - frictional energy - gravitational energy - emotional energy - kinetic energy A:
kinetic energy
Q: Answer the following question given this paragraph: Homeostasis refers to the balance, or equilibrium, within the cell or a body. It is an organism's ability to keep a constant internal environment. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is referred to as homeostatic regulation. Because the internal and external environments of a cell are constantly changing, adjustments must be made continuously to stay at or near the normal proportions of all internal substances. This involves continual adjustments in transport of substances across the cell membrane. Homeostasis is a dynamic equilibrium rather than an unchanging state. The cellular processes discussed in the cell transport (passive and active transport) concepts all play an important role in homeostatic regulation. Q: What term means the adjusting of systems within a cell in order to restore balance or maintain equilibrium? Choices: - systemic regulation - aftertouch regulation - gaseous regulation - homeostatic regulation A:
A: homeostatic regulation
Question: Answer the following question given this paragraph: Q: When does an oocyte complete meiosis? Choices: - metaphase - prophase - anaphase - after sperm penetration A:

Answer the following question given this paragraph: Chuck Szmurlo (Wikimedia: Cszmurlo). Nuclear power is generated using a nonrenewable resource . CC BY 2.5. Q: What type of power is generated using a nonrenewable resource? Choices: - wind power - solar power - water power - nuclear power A:
**Answer**
nuclear power
Answer the following question given this paragraph: When organisms die, they leave behind energy and matter in their remains. Decomposers break down the remains and other wastes and release simple inorganic molecules back to the environment. Producers can then use the molecules to make new organic compounds. The stability of decomposers is essential to every ecosystem. Decomposers are classified by the type of organic matter they break down:. Q: What do decomposers release back to the environment after they break down the remains and other wastes? Choices: - carbon monoxide - unrefined waste - nematodes - simple inorganic molecules A:
simple inorganic molecules
