Enzymes, vitamins and hormones can be classified into a single category of biological chemicals, because all of these:
- enhance oxidative metabolism
- are conjugated proteins
- are exclusively synthesized in the body of a living organism as at present
- help in regulating metabolism
The Correct Option is D
Solution and Explanation
Enzymes facilitate chemical reactions in metabolism, vitamins are essential coenzymes and cofactors that assist enzymes, and hormones are chemical messengers that regulate various metabolic processes in the body.
So, the correct option is (D): help in regulating metabolism

A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :

- Two cities X and Y are connected by a regular bus service with a bus leaving in either direction every T min. A girl is driving scooty with a speed of 60 km/h in the direction X to Y. She notices that a bus goes past her every 30 minutes in the direction of her motion, and every 10 minutes in the opposite direction. Choose the correct option for the period T of the bus service and the speed (assumed constant) of the buses.

Enzymes - Biology
Enzymes are proteins that help accelerate metabolism or the chemical reactions in our bodies. They build some substances and decompose others. All living creatures have enzymes.
Our bodies naturally build enzymes. But enzymes are also in mass produce products and food.
One of the most important roles of enzymes is to succor digestion. The process of turning the food that we eat into energy is called digestion. For instance, there are enzymes in our saliva, pancreas, stomach, and intestines. They decompose fats, proteins, and carbohydrates. Enzymes make use of these nutrients for growth and cell repair.
