Answer:
Cyanide may cause muscle weakness because tissues are not able to use oxygen for cellular respiration
Explanation:
Cyanide is a highly toxic compound that inhibits cellular respiration by inactivating cytochrome oxidase in mitochondria, which is a key enzyme responsible for oxidative metabolism and energy production. Thus, cyanide consumption decreases the utilization of oxygen by muscle cells, thereby causing weakness. The symptoms of cyanide poisoning include, among others, weakness, malaise, visual disturbances, muscle pains, etc.
Answer:
Explanation:
An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.
The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support.
Enzymes are produced naturally in the body.
For example, enzymes are required for proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine. But even your salivary glands produce digestive enzymes to start breaking down food molecules while you’re still chewing. You can also take enzymes in pill form if you’re having certain digestive problems.
The cell membrane is very important to the cell structure. It helps hold everything within the cell and serves as a protective covering as well.
Answer:
Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body
Answer:
Photosynthesis takes place in two stages, namely light-dependent reactions and light-independent reactions. Light-dependent reactions are also called light reactions and occur during the day time. Light-independent reaction is also called the dark reaction or the Calvin cycle.
