(i) Constitutive enzymes are the ones that are produced in the cell regardless of environmental conditions.

Induced enzymes are the ones that are produced only under the effect of certain factors.

(ii) Metabolic regulation is regulation of catabolic and anabolic pathways by altering the activity of enzymes.

(iii) Product inhibition is the ability of product of reaction or metabolic pathway to reduce the activity of enzyme that contributes to its formation.

<ol><li>Explain the effects of triton on the activities of each of the enzymes (MDH and LDH). </li><li>Explain the observed distribution of the enzymes in terms of their metabolic roles. </li></ol>

1.On addition of triton to both enzymes MDH and LDH it renatures them. 2. Enzymes are proteins that act as biological catalysts (biocatalysts). Catalysts accelerate chemical reactions. The molecules upon which enzymes may act are called substrates,...

Name a few different plant defense strategies. What is the difference between an induced and a constitutive defense in plants?

Plant defence strategies comprise:1. Mechanical defence: bark, waxy cuticles,  thorns, spines, etc.2. Chemical defence: toxins and alkaloids (i.e., volatile oils of mint, quinine, caffeine, glycol cyanide), enzymes, etc.A constitutive defence...

1) Enzymes are in which state of matter (solid, liquid, gas)? 2) Can enzymes be converted into solid state? 3) Do enzymes function if they are converted into solid state?

Solution1.Enzymes are generally in fluid form to enable them carry out metabolic functions2. Enzymes can be converted to solid state3. Converting leads to denaturing of the enzymes, the active side...

Why does an endotherm’s metabolic rate increase above the upper lethal temperature? And why does the metabolic rate fall below the lower lethal temperature?

Above the upper lethal temperature, an endotherm’s metabolic rate increases to expend energy that will be used to lose heat. As a result, increased metabolic rate causes sweating that stimulates...
