When too high or too low physiological activities cease primarily because molecules are destroyed or become nonfunctional?
When physiological activities are too high or too low, it can disrupt the functioning of molecules essential for these activities. In extreme cases, these molecules can be destroyed or rendered nonfunctional due to the imbalance, leading to a halt in physiological processes and potentially causing harm to the organism. Maintaining a balance in physiological activities is crucial for proper functioning of the body.

Why do humans suffer ill effect if their body temperature varies too much?
Because we belong to a group called endotherms, which means that we regulate our body temperatures. It takes a lot more energy to do this than it does for ectotherms, like reptiles, but the advantages are that we can function in larger extremes of temperatures. That's why endotherms like polar bears and penguins can be found in the arctic and antarctic regions.
Enzymes are affected by both pH and?
Enzymes are affected by both pH and temperature. Changes in pH can alter the shape and charge distribution of the enzyme, affecting its ability to bind to substrate molecules and catalyze reactions. Extreme pH levels can denature the enzyme and render it nonfunctional.
What are they biochemical disturbances?
Biochemical disturbances refer to abnormalities in the levels or activities of molecules involved in biological processes. These can include imbalances in hormones, enzymes, neurotransmitters, or other chemicals that can disrupt normal physiological functions and lead to various health issues. Identifying and understanding these disturbances is important for diagnosing and treating related diseases.
How do ATP molecules provide energy for cellular activities?
ATP molecules provide energy for cellular activities by releasing energy when the phosphate group is broken off, creating ADP and a phosphate molecule. This energy release powers various cellular processes, such as muscle contraction, protein synthesis, and active transport.
How are proteins destroyed and what factors contribute to their degradation?
Proteins are destroyed through a process called proteolysis, where enzymes break down the protein molecules into smaller fragments. Factors that contribute to protein degradation include pH levels, temperature, presence of enzymes, and oxidative stress.

How many ozone molecules are destroyed every day?
Ozone molecules are destroyed everyday by CFC's. This number depends upon the current season.
Describe what the ozone layer is how humans have destroyed it?
Ozone layer is a layer of ozone molecules. It is destroyed by man made CFC's.

What happens to the molecules during melting?
the order of the solid molecule is destroyed, the molecules can move more freely, while in solids the molecules vibrate in fixed point
How does the ozone leyer is destroy?
The ozone layer is destroyed by certain chemicals, such as chlorofluorocarbons (CFCs) and halons, which break down ozone molecules in the stratosphere. This destruction is primarily caused by human activities like industrial processes and the use of certain products like aerosol sprays and refrigerants. When these chemicals reach the ozone layer, they release chlorine and bromine atoms that catalytically destroy ozone molecules.
What is a physiological change as a result of a catabolic chemical reaction?
Catabolism is the breaking down of things - a series of degradative chemical reactions that break down complex molecules into smaller units, and in most cases releasing energy in the process. ~One physiological changes is digestion of large food molecules into various nutrients.
What is a major eicosanoid?
A major eicosanoid is a bioactive lipid derived from arachidonic acid, a polyunsaturated fatty acid. Eicosanoids play crucial roles in various physiological processes, including inflammation, immune response, and blood clotting. Key classes of eicosanoids include prostaglandins, thromboxanes, and leukotrienes, each with distinct functions in the body. These molecules serve as important signaling molecules, modulating various biological activities.
What chemical reactions take place in the body are called?
The chemical reactions that take place in the body are collectively known as metabolism. Metabolism encompasses two main types of reactions: catabolic reactions, which break down molecules to release energy, and anabolic reactions, which build up molecules for growth and repair. These processes are essential for maintaining life, supporting cellular functions, and providing energy for various physiological activities.
What are molecular functions?
Molecular functions refer to the specific biochemical activities performed by individual molecules, particularly proteins, within a biological system. These functions include processes like enzyme catalysis, binding to other molecules, and signal transduction. Molecular functions are essential for the overall functioning of cells and organisms, as they enable various physiological processes and interactions. Understanding these functions is crucial for fields such as biochemistry, genetics, and biotechnology.
Briefly describe how Avery and his group determined which molecules was most important for transformation?
Avery and his colleagues made an extract, or juice, from the heat-killed bacteria. They then carefully treated the extract with enzymes that destroyed proteins, lipids, carbohydrates, and other molecules, including the RNA. Transformation still occurred. Obviously, since these molecules had been destroyed, they were not responsible for the transformation. Your welcome:)
