All of the following statements about enzymes are true EXCEPT
kari74 [83]

Answer:

(D) Enzymes can function only within living cells.

Explanation:

<em>Enzymes are biological molecules that are proteinous in nature and speed up the rate of biological reactions.</em>

Option A is true because enzymes are not used up or changed when they are used to catalyze reactions

Option B is true. Enzymes are very specific with regards to the reactions they take part in.

Option C is true. Some enzymes contain non-protein component that assist them in their functioning. These non-protein components are called co-factors.

Option E is true. Because enzymes are proteinous in nature, they can be destroyed/denatured by high temperatures.

<em>The only untrue option is D. Some enzymes can function outside living cells. For example, the enzymes involved in digestion can function not just within living cells but also outside it. The functions of some of the digestive enzymes can be demonstrated in the laboratory.</em>

The correct option is D.

love history [14]

The right approaches to population monitoring methods of swallows and tortoises are point counts and line-transect distance sampling, respectively.

  • For point counts, In order to collect the data required to meet the current study's objectives, one must use field techniques methods for selection, counting, capturing, observing, measuring, and marking individuals chosen from the targeted population.
  • To count or keep track of the birds of the air, point counts are a frequent field technique (birds).
  • The practice involves making observations over a predetermined, set amount of time and keeping track of the number of birds coming from a specific location.
  • While the line-transect distance sampling methods in the field are useful for keeping track of the number of tortoises and is appropriate for controlling and tracking the population.
