Ques: What are enzymes? How do they work?
Ans: Enzymes are biological catalysts that catalyze reactions with minimum activation energy; thus, metabolic processes run rapidly.
Ques: What is the role of chlorophyll in photosynthesis?
Ans: Chlorophyll absorbs light energy, mainly solar energy, and changes it into chemical energy during photosynthesis for the production of glucose.
Ques: What is the role of haemoglobin in blood?
Ans: Hemoglobin is a red blood cell protein that captures oxygen in the lungs to carry it to tissues throughout the body.
Ques: What is a synapse?
Ans: It is a junction between two neurons where nerve impulses pass from one neuron to another by chemical or electrical signal.

Hello Pruthvi,
Taking a drop year to reappear for the Karnataka Common Entrance Test (KCET) is a well-defined process. As a repeater, you are fully eligible to take the exam again to improve your score and secure a better rank for admissions.
The main procedure involves submitting a new application for the KCET through the official Karnataka Examinations Authority (KEA) website when registrations open for the next academic session. You must pay the required application fee and complete all formalities just like any other candidate. A significant advantage for you is that you do not need to retake your 12th board exams. Your previously secured board marks in the qualifying subjects will be used again. Your new KCET rank will be calculated by combining these existing board marks with your new score from the KCET exam. Therefore, your entire focus during this year should be on preparing thoroughly for the KCET to achieve a higher score.

Yes, you can switch from Science in Karnataka State Board to Commerce in CBSE for 12th. You will need a Transfer Certificate from your current school and meet the CBSE school’s admission requirements. Since you haven’t studied Commerce subjects like Accountancy, Economics, and Business Studies, you may need to catch up before or during 12th. Not all CBSE schools accept direct admission to 12th from another board, so some may ask you to join Class 11 first. Make sure to check the school’s rules and plan your subject preparation.
