During exercise, muscle cells immediately use ATP as the energy source for contractions.

The only immediate source of energy for muscular contraction is ATP. Within muscle fibers, ATP is replenished by creatine phosphate (anaerobic respiration), glycolysis (anaerobic respiration), and cellular respiration (aerobic respiration). As the duration and intensity increase, carbohydrates (glucose/glycogen) become the primary source of fuel. If exercise is sustained for an extended period of time, fatty acids will be used as a fuel source when glycogen stores are nearly depleted.

ATP is a form of instant energy. The body cannot obtain energy directly from glucose. Glucose is not a direct source of energy. Instead, the body uses the energy released from the breakdown of glucose to drive ADP phosphorylation.

You are given a 1 liter bacterial culture in exponential stage of growth. The generation time of the bacteria is known to be 30
nydimaria [60]

Answer:

Option-A

Explanation:

A bacteria divides by binary fission which divides a parent bacteria into the two daughter cells and generation time refers to the average time difference between two consecutive generations.

The bacterial cell grows by the exponential function that is by 2^{number of generation} x initial population of bacteria.

In the given question,

<u>Initial population</u>

the initial population of bacteria - 2x 10³ per ml

So per liter, the bacterial population will be 2 x 10 ⁶

<u>Generation time</u>

1 generation time of bacteria is 30 min.

so 5 hours will have- <u> </u>\frac{300}{30}= 10 generations

<u>New bacterial population</u>

Using formula<u>  </u>2^{number of generation} x initial population of bacteria

2^{10} x (2 x 10⁶)

= 1048 x (2 x 10⁶)

2048 x 10⁶

Thus, Option-A is the correct answer.

Holding the horse's lead rope is necessary, when restraining a horse for a routine veterinary procedure by the veterinary assistant.

Always hold the lead rope in the right hand by coiling the excess rope on the hand in the other hand.

Lead the left shoulder of the horse with the assistant's right hand with the excess of rope in the left hand of the assistant to avoid serious injury when the horse decides to bolt.

It becomes important to stable the horse by calming the horse before the routine veterinary procedure.

A leather band should be used in the rope by being tightened behind the legs of the front and by further fastening.

Remember not to harm the back of the horse by excessive fastening.
