Question

Check POINT 1-

1. Define respiration.
2. Which substrate is used by cells for producing energy? -

4. Give the overall reaction of respiration.
5. Why do we feel muscle cramps after a fast running?
6. Give one example of an anaerobic plant and an anaerobic animal.
7. What is the end product of anaerobic respiration in skeletal muscles?​

Answer 1

Answer:

hey mate, here are ur answers:-

Ans 1. a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

Ans 2. Glucose.

Ans 4.Respiration is the process where the food is oxidized in the presence of oxygen by the certain respiratory enzyme and it leads to the production of 38 ATP. C6 H12 O6 +6O 2 →6CO2 +6H 2 O+Energy(2900 kJ)

Ans 5.such cramping was believed to arise from dehydration, electrolyte imbalances (including magnesium, potassium and sodium), accumulation of lactic acid, or low cellular energy levels.

Ans 6. aerobic:-Human ,dogs ,cats and all the animals and birds ,insects ,grasshopper etc many more and most of the plants carry out aerobic respiration

anaerobic:-Yeast is an organisms which can live without the oxygen of air because it obtains energy by the process of anaerobic respiration .

Ans. 7. Lactic acid and AtP molecules

Hope this will help u. and if it does,plz let me know by making this answer brainliest!! thanks!!

Answer 2

Answer:

1) respiration:- the process by which living thing produce energy from food.Respiration usually need oxygen .

2)Adenosine triphosphate ( ATP) is the substance used by cell for producing energy.

4)aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide ,water energy and involve an electron transport system in Vich molecules oxygen is the final molecules acceptor.

5) cramps can occur when molecules are unable to relax properly due to myosin protein not fully detaching from actin filament.
