Define co-factor and Co-enzyme.
Co-factor
Non-protein chemical compound (organic or inorganic) that is required for an enzyme to function appropriately is called co-factor.
Co-factors perform their actions oftenly through loosely or tightly binding with active site of enzymes.Usually, co-enzymes are metal ions, i. e., Cu++, Fe++, Co ++, Mg++ etc.
Co-enzyme
Co-enzyme is a type of co-factor that is organic compound loosely bonded with enzymes.
Mostly, co-enzyme are vitamins or are derivatives of vitamins, i.e., Vitamin A, D, E, K, etc. Without Co-enzyme, enzymes do not perform action as an enzyme.

T he Federal Board of Intermediate & Secondary Education (FBISE) is an autonomous body that conducts the examinations in the institutions affiliated with it in Pakistan as well as abroad. Punjab government has ten boards of Intermediate & Secondary Education including Bahawalpur Board, D.G. Khan Board, Faisalabad Board, Gujranwala Board, Lahore Board, Multan Board, Rawalpindi Board and Sargodha Board and each board conducts exams independently. Federal Board generally follows the international norms and standards. Federal Board paper pattern is quite tricky and similar to O-Level and A Level formats. These questions need conceptual approach to be solved. Punjab board’s Paper pattern is comparatively easy up to some extent. We are currently focusing on the subject of Chemistry for all classes affiliated with Federal Board ( IX , X , XI , XII ) and Punjab Board ( XI XII ). We intend to extend it to all subjects i...

Basic Definitions| Matter, Substance, Element, Compound. Mixture, Homogeneous mixture and Heterogeneous mixture Examples (for Grade - 9 students)

Basic Definitions| Matter, Substance, Element, Compound. Mixture, Homogeneous mixture and Heterogeneous mixture Examples (for Grade - 9 students) Question: Define following terms: Matter Substance Element Compound Mixture Homogeneous mixture Heterogeneous mixture Answer Matter: Matter can be anything that occupies space (volume) and has mass. Example, book, table, walls, chairs, plants, animal, etc. Substance: Substance is a matter that has a particular set of characteristics that differ from the characteristics of another kind of matter. For example, oxygen, water, carbon monoxide, carbon dioxide, urea, glucose, common salt etc are different substances. Element: A substance that cannot be converted to other simpler substances is known as an element. or A substance which has all atoms of same atomic number is called element. For example substances like oxygen, hydrogen, iron, copper, aluminum etc. are elements. Compound: ...

Experimental Techniques in Chemistry

Analytical Chemistry: The branch of chemistry that deals with the quantitative and qualitative analysis of substances is called Analytical Chemistry. Question 2.1: What is difference between quantitative and quantitative analysis? What are various steps involved in quantitative analysis? Answer: Qualitative analysis: The analysis in which elements are identified is called qualitative analysis. Quantitative analysis: The analysis in the form of which relative amounts of elements are determined is called quantitative analysis. There are four main steps involved in quantitative analysis. 1. Obtaining a sample for analysis 2. Separation of desired constituent 3. Measurement and calculations of results 4. Drawing conclusions from analysis Question 2.2: Define filtration. How do we select the filter media? Answer: The process of separating solids or suspended particles from liquids by using a filter medium is called filtration. Question...

Alkyl halides

The compounds in which one hydrogen atom of alkane is replaced by a halogen atom is called alkyl halide. Alternatively, The halogen derivatives of alkanes with general formula R-X are Halide called alkyl halide. For example CH4 ( Alkane ) CH3-X ( Alkyl halide ) X = F, Cl, Br and I Table Of Contents Types Mono, di, tri or poly haloalkane depending upon the number of halogen atom. For example C lassification of Alkyl Halides Alkyl halides can be classified as primary, secondary and Tertiary alkyl halides. 1.

Shielding Effect (Grade 9 Students) and its trend in Periodic Table.

Question: What is shielding effect? Give its trends in the periodic table. Answer . Shielding Effect The decrease in force of attraction between nucleus and valence electrons due to presence of inner shell electrons is called shielding effect. It is also known as screening effect. It increases with increase in inner shell electrons. For example, Mg has greater shielding effect than Be. This is because Mg has eight more inner-shell electrons than Be. Trend in Periodic Table In period As we move from left to right in a period, shielding effect remains constant. Reason is that the number of inner shell electrons remains constant along the period. In group As we move from top to bottom in a group, shielding effect increases. This is due to fact that the number of inner shell increases and hence, inner shell electrons also increase. For example, Na has greater shielding effect than Li because of eight more inner shell electrons than Li...

Class 9 Electrochemistry MCQs and Answers with explanation

1. In which of the following changes, the nitrogen atom is reduced? a) N 2 to NO b) N 2 to NO 2 c) N 2 to NH 3 d) N 2 to HNO 3 ... Answer is b) Explanation: Oxidation number of an elemnet in free state is zero. So Oxidation No. of N 2 = 0 Calculate oxidation No. of nitrogen in each compound. Option a) Let, oxidation No. of N in NO is X. Sum of oxidation numbers of all atoms present in a neutral compound is zero. Oxidation No. of N + (Oxidation No. of O ) = 0 X-2 = 0 X = +2 X = +2 Oxidation No. of N in NO 2 is +2 Option b) Let, oxidation state of N in NO 2 is X. Sum of oxidation numbers of all atoms present in a neutral compound is zero. Oxidation No. of N + 2(Oxidation No. of O ) = 0 X + 2(-2) = 0 X -4 = 0 X = +4 Oxidation No. of N in NO 2 is +4 Option c) Let, oxidation state of N in NH 3 is X. Sum of oxidation numbers of all atoms present in a neutral compound is zero. Oxidation No. of N + 3(Oxidation No. of H )...
