اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Each mole of ATP (Adenosine Triphosphate) stores energy equivalent to:
7.3 kilocalories (kcal) per mole (approximately) 17.3 kilojoules (kJ) per mole (approximately)
الیکٹران اور پروٹون کی کمی کو _____ کہتے ہیں؟
Oxidation reaction
Reduction reaction
Redox reaction
All of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The loss of electrons and protons (H+ ions) is called oxidation. Oxidation is a chemical reaction that involves the loss of electrons or the addition of oxygen. Resulting in a change in the oxidation state of an atom, molecule, or ion.

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
In cellular respiration, each mole of glucose typically produces about 36-38 ATP molecules.
To determine how many moles of glucose are consumed to produce 180 ATP molecules, we can use the following calculation:
180 ATP/36 ATP or mole of glucose = 5 moles of glucose
Thus, 5 moles of glucose are consumed to produce 180 ATP molecules.
ایروبک سانس لینے کا مرحلہ مائٹوکونڈریا کے کرسٹے پر ہوتا ہے جسے _____ کہتے ہیں؟
Electron transport chain
Glycolysis
Kreb's cycle
C3 cycle
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The electron transport chain (ETC) is the stage of aerobic respiration that takes place at the cristae of mitochondria. The cristae are specialized infoldings of the mitochondrial inner membrane, where the ETC complexes are embedded.

Explanation
The energy released (14135 KJ) is equivalent to the energy released from the oxidation of glucose (C6H12O6), which is typically around 2820 KJ/mol.To find the number of moles of glucose consumed , you can divide the energy released (14135 KJ) by the energy released per mole of glucose (2820 KJ/mol):14135 KJ ÷ 2820 KJ/mol = 5 mol
مندرجہ ذیل میں سے کون سا مظاہر اس وقت ہوتا ہے جب پانی کے بخارات دھوئیں کے ذرے کے گرد گاڑھا ہو جاتے ہیں؟
Fog
Hail
Mist
Smog
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
When water vapour in the air condenses and accumulates around a dust particle near the ground, fog is formed.
Cloud of small water droplets near ground level that is dens e enough to reduce horizontal visibility to less than about 3,000 ft (1,000 m).
Fog may also refer to clouds of smoke particles (smog), ice particles, or mixtures of these components.
تالا اور کلیدی ماڈل کے بارے میں صحیح بیان کا انتخاب کریں؟
Enzyme and substrate posses' specific complementary geometric shapes
Active site of enzyme is flexible
Active site continuously changes
All above statements are correct
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The lock and key model proposes that the enzyme and substrate have specific, complementary geometric shapes that fit together perfectly, like a key fitting into a lock. This means that the active site of the enzyme is a rigid, pre-formed structure that perfectly complements the shape of the substrate.
درجہ حرارت ______ ہونے پر رد عمل کی شرح بڑھے گی؟
Increases
Decreases
Below 10°C
Both A and B
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The rate of a chemical reaction typically increases when the temperature increases. As higher temperatures provide more energy for the reactant molecules to collide and react.
انزائم کی سرگرمی کو متاثر کرنے والے تمام عوامل ہیں سوائے؟
pH
Substrate concentration
Organic solvent
Temperature
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Organic solvents are not a typical factor that affects enzyme activity.In fact, many enzymes are denatured or inactivated in the presence of organic solvents. As they can disrupt the enzyme's native structure and function.
کیمیائی رد عمل کو مناسب شرح سے نیچے لے جانے کے لیے خاص حالات کی ضرورت ہوتی ہے، خاص طور پر؟
Temperature and Nature
Nature and Pressure
Nature and Structure
Temperature and Pressure
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Chemical reactions require specific conditions to proceed at a proper rate. Temperature and pressure are two of the most important factors that influence reaction rates.
