Q1. Name the alkaloid toxicant in Potato?

1. Piperine
2. Cocaine
3. Capsaicin
4. Solanine

ANSWER –  D. Solanine

• Explanation – Alkaloid toxicant in Potato is Solanine. A potato’s green half should be discarded. It’s bitter, and it also includes solanine, which can make you sick if consumed in large amounts. Solanine is a colorless alkaloid with a bitter taste. Diarrhea, fever, or a lower-than-normal body temperature (hypothermia), headache, and other symptoms of solanine poisoning can occur. To avoid solanine poisoning, peel the green and “eyes” off a potato before cooking.

Q2. Identify Extrinsic Parameters Affecting Microbial Growth?

1. Water activity
2. pH
3. Temperature
4. Acidity

ANSWER: C. Temperature

• Explanation: Microbes have a growth temperature optimum, as well as minimum and maximum temperatures. As a result, the temperature of the environment influences not only the pace of proliferation but also the types of microorganisms that survive and the amount of microbial activity that happens. Most microorganisms thrive at temperatures ranging from 150 to 400 C. Many microbe genera, on the other hand, can thrive at temperatures ranging from 0 to 150 C, and even microorganisms can grow at subzero temperatures.

Q3. __________ can thrive in a too acidic medium.

1. Acidophilic Bacteria
2. Yeast
3. Mold
4. All the above

ANSWER: A. Acidophilic Bacteria

• Explanation – Most microorganisms require a pH close to neutral for optimal development (7.0). Yeasts may develop in an acidic environment, but they thrive in a pH range of 4.0-4.5. Molds may develop in a larger pH range (2.0-8.0), although their growth is often faster when the pH is acidic. Molds can flourish in an acidic environment that is unsuitable for bacteria or yeasts. Near-neutral pH levels are typically favourable for bacterial development. Acidophilic (acid-loving) bacteria, on the other hand, will thrive on food or trash down to a pH of around 5.2.

Q4. Enterotoxin is a type of __________?

1. Infection in nervous system
2. infection in intestine
3. Intoxication in intestine
4. Intoxication in nervous system

ANSWER – C. Intoxication in intestine

• Explanation: The presence of the organism in the food is irrelevant to disease production. It is the toxin that gives rise to the disease. Bacterial toxins that produce intoxications are exotoxins that are either enterotoxins affecting the gut, as in the disease caused by Staphylococcus aureus, or neurotoxins, as in the disease caused by Clostridium botulinum, the toxin in this case affecting the nervous system.

Q5. Zoonotic means Micro organism naturally found in?

1. Air
2. Animals
3. Water
4. Plants

ANSWER:  B. Animals

• Explanation: Known as zoonotic illnesses or zoonoses, animals can occasionally carry hazardous bacteria that can transmit to humans and cause illness. Viruses, bacteria, parasites, and fungi are all responsible for zoonotic illnesses. These bacteria may cause a variety of ailments in humans and animals, ranging from minor to severe, and even death.
