━━━━━━━━━━━━━

Answer -

1. Steps of respiration are -

$\implies$Breathing

$\implies$Glycolysis

$\implies$Kreb cycle

$\implies$Electron transport System

━━━━━━━━━━━━━

2. Glycolysis is the process in which glucose is converted into Pyruvic Acid in presence of enzymes and co enzymes.

$\implies$Oxygen is not required. Formation of $CO_2$ does not takes place.

$\implies$It occurs in the cytoplasm of cell.

━━━━━━━━━━━━━

3. Kreb cycle is the process in which the conversion of Pyruvic Acid, fatty acids , fats, amino acids into $CO_2$and water by oxidation takes place.

$\implies$It is common path for oxidation of carbohydrates,fats and proteins.

$\implies$It occurs in Mitochondria of cell.

━━━━━━━━━━━━━

4. ATP - ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

$\implies$Full Form - Adenosine Triphosphate.

━━━━━━━━━━━━━

ADP - ADP is an ingredient for DNA, it's essential for muscle contraction and it even helps initiate healing when a blood vessel is breached.

$\implies$Full Form - Adenosine Diphosphate.

━━━━━━━━━━━━━

5. $\implies$Site of glycosis - Cytoplasm of cell.

$\implies$Site of Kreb cycle - Mitochondria of cell.

━━━━━━━━━━━━━

6. Glycolysis is the main metabolic path of cellular respiration for the production of energy. The importance of glycolysis is to take glucose and break it down into 2 pyruvate molecules, 2 NADH and 2 ATP.

━━━━━━━━━━━━━

7. Stomata and lenticles are both responsible for gaseous exchange in plants. They are small pores present in the body of plants.

━━━━━━━━━━━━━

8. A control is a set-up used to show that the experiment is valid. It's a setup where no variables are tested.A control set-up "controls" for other factors.

$\green{\underline{{ \sf{ Question :-}}}}$

What are the phases of Respiration?

$\blue{\underline{{ \rm Answer :-}}}$

The phases of respiration are :-

1. Inhalation or Inspiration
2. Exhalation or Expiration

• Inhalation/Inspiration :- This is the process in which air or any other gas enter our body through our lungs.

• Exhalation/Expiration :- This is is the process in which year or any other gas flows out of our body.

$\green{\underline{{ \sf Question :-}}}$

What is glycolysis?

$\blue{\underline{{ \rm Answer :-}}}$

The process by which glucose (C₆H₁₂O₆) breaks down into CH₃COOH i.e this is the process, in which there is breakdown of glucose.

$\green{\underline{{ \sf Question :-}}}$

What is kreb's cycle ?

$\blue{\underline{{ \rm Answer :-}}}$

Kerb cycle also known as Citric acid cycle (CAC) or Tricarboxylic acid cycle (TCA) , via this, energy is released during aerobic respiration.

$\green{\underline{{ \sf Question :-}}}$

Write the full form of ATP and ADP.

$\blue{\underline{{ \rm Answer :-}}}$

• ATP :- Adenosine tri-phosphate
• ADP :- Adenosine di-phosphate

$\gray{\underline{{ \rm Question :-}}}$

What are the sites of glycolysis and Kreb's cycle?

$\green{\underline{{ \sf Question :-}}}$

Why is glycolysis considered as an important stage of respiration?

$\blue{\underline{{ \rm Answer :-}}}$

Glycolysis is considered as an important stage of respiration Because :-

• It's the first & main pathway to cellular respiration
• Glycolysis, is only which produces energy in the form of ATP

$\green{\underline{{ \sf Question :-}}}$

State the common function performed by stomata and lenticels.

$\blue{\underline{{ \rm Answer :-}}}$

Some common function performed by stomata and lenticels are :-

• They both are small pore like opening on a plant.
• Both of them are responsible for exchange of gas.
• Both of them let the water vapour go in the atmosphere.
• They both are composed of living cell.

$\green{\underline{{ \sf Question :-}}}$

What is control set- up?

$\blue{\underline{{ \rm Answer :-}}}$

This means that whatever the experiment you are doing is correct & accurate.
