Answer:
Enzyme: A biomolecule that speed up the rate of chemical reactions without being used up.
Substrate: A substance or chemical that enter the chemical reaction and is being converted into a new substance (product).
Competitive enzyme inhibition: Inhibition of enzyme's activity by binding of inhibitor to substrate binding site of the enzyme.
Explanation:
Enzymes are the biomolecules that serve to increase the rate of reactions by lowering down the required activation energy. The enzyme is never used up during reactions.
Substrates are the chemicals that undergo a chemical change and produce products.
For example, Glucose is the substrate for hexokinase enzyme and is converted into glucose 6 phosphate (the product).
When the inhibitor competes with the substrate for the binding site on the enzyme and does not allow the substrate to bind to the enzyme, the process is called competitive enzyme inhibition. It can be overcome by increasing the concentration of substrate in the system.
The cell would fall apart it has no walls to hold it together
The preoperational stage is one of the many stages of a child's development. Piaget states that the most obvious change during the preoperational stage is the increase in a child's use language as a symbol or tool for communication. Though they can use language as symbols, they are still not able to form logic or transform ideas into understandable information.
Because their TEETH ARE MISALIGNED AND THEY USUALLY POSSESS LONG TONGUE. Respiratory illness is common in people who have down syndrome and their unique airway anatomical factors makes airway management difficult during respiratory distress. For instance, they have narrower upper airway and smaller trachea.
