Explanation

• The rate of a chemical reaction typically increases when the temperature increases.
• As higher temperatures provide more energy for the reactant molecules to collide and react.

Explanation

• Organic solvents are not a typical factor that affects enzyme activity.
• In fact, many enzymes are denatured or inactivated in the presence of organic solvents.
• As they can disrupt the enzyme's native structure and function.

Explanation

• Chemical reactions require specific conditions to proceed at a proper rate.
• Temperature and pressure are two of the most important factors that influence reaction rates.

Explanation

• The mismatched pair is: Proteases → Carbohydrate
• Proteases are enzymes that break down proteins, not carbohydrates.

Explanation

• The induced fit model proposes that the active site of an enzyme is flexible and changes shape until the substrate binds, much like a glove molding to fit a hand.
• This model suggests that the enzyme adapts to the substrate, rather than the substrate simply fitting into a pre-existing lock.

Explanation

• Optimum pH is the point where an enzyme is most active.
• It is the pH at which the enzyme catalyzes the reaction at its maximum rate. 
• Different enzymes have different optimum pH values, depending on their structure and function.

Explanation

Metabolic reactions are both constructive (anabolic) and destructive (catabolic) reactions.

Explanation

• Inhibitors are molecules that bind to enzymes and decrease their activity, thereby slowing down or preventing the biochemical reaction.
• Enzyme activity is not enhanced by inhibitors, but rather inhibited.

Explanation

• Non-disjunction is the phenomenon where a pair of homologous chromosomes (or a pair of sister chromatids) fails to separate properly during meiosis.
• Resulting in an abnormal number of chromosomes in the daughter cells.
• This can lead to genetic abnormalities, such as Down syndrome (trisomy 21), or other chromosomal disorders.

Explanation

• In Anaphase-II of meiosis, the centromeres shorten and the paired chromatids (sister chromatids) are pulled away from one another, moving to opposite poles of the cell.
• This is the stage where the genetic material is finally separated, and each pole receives a complete set of chromosomes.
