Is the correct order in a homeostatic feedback system stimulus, receoptor, control centre, effector?
Fantom [35]

Answer:

Correct

Explanation:

Homeostatic is nothing but ability of a system or living organism to manipulate its internal environment to maintain a stable equilibrium, for example the ability of warm-blooded animals to ascertain a constant body temperature.

The Homoeostatic feedback mechanism has three basis components and they are independent to one another.

These components are receptor, effector and integrating center. The function of receptor is to sense external stimuli and send information to integrating center. The integrating center generally hypothalmus in brain sends this signal to effector for example an organ to react to the stimuli.

So, the order  in a homeostatic feedback system stimulus, receoptor, control centre, effector is correct.

The atp required for continuous muscle contraction during endurance activities comes from?
maw [93]

The ATP required for continuous muscle contraction during endurance activities comes from anaerobic respiration and oxidative phosphorylation.

<h3>What is anaerobic respiration? </h3>

The process of breakdown of substrate glucose in the absence of oxygen is called anaerobic respiration. This process primarily takes in some unicellular organisms.

In humans, during endurance activities, a continuous supply of ATP is required. The ATP reserves in muscles are very small. Thus, there is a requirement for metabolic pathways to maintain continuous ATP supply and resynthesis.

These pathways are phosphocreatine breakdown and muscle glycogen breakdown which enable anaerobic substrate level phosphorylation and aerobic phosphorylation.

Therefore, the ATP required for continuous muscle contraction during endurance activities comes from anaerobic respiration and oxidative phosphorylation.
