Confused about metabolism?

Hey guys!
So basically I've been really confused and I have no one to help me with it .

Basically u was stuck on this topic on thermoregulation which is part of homeostasis. I study A2 biology and exam board is AQA

I want to know if this is right and can SOMEONE PLEASE PHRASE THIS PROPERLY! I don't know how to 😭😭😭;
Increasing temperature- leads to decrease in the need of food uptake- this is because there is increase in enzyme activity and hence there is a higher rate of/ more ( I don't which one is right ? Is it both of them) respiration. This means that there is faster metabolism of more food and so there is more heat released.

My problem is - what does metabolism mean in simple English ? I know metabolic rate is the speed at which chemical reactions like respiration occur .

My other question is metabolic rate the same as the rate of reaction ?
Also the main question is how exactly does eating food generate heat ? Including all the steps I'm mentioned ?

Thinking about the rephrasing part, I'm not sure what question you are trying to answer but I would say it more like this:
An increase in temperature leads to an increase in enzyme activity and hence, a higher rate of respiration. This means that there is a higher metabolic rate and so more heat energy is released. This in turn, leads to a decreased food uptake.

You guys think that burning more energy leads to less oral intake?

I wasn't really sure about that, I know more about animal physiology (I'm studying veterinary) and the basic idea there is that in summer higher temperatures mean that there is more food available so animals use more energy to find food and the greater food intake leads to a catabolic state. In the winter cooler temperatures mean there is less food available so animals spend less time foraging, and consequently less energy is spent on looking for food (relatively speaking) so there is a lower food intake and the body uses up reserves gained in the summer months and is in an anabolic state.
Thinking about that made me confused about the thermoregulation side of things but physiologically it makes sense to reduce heat producing activities if the body is in danger of becoming hyperthermic but I'm not sure how much of an effect it would have on a day to day basis when hyperthermia is not a risk.

I don't think you understand what anabolism and catabolism are! How can an animal be anabolic, i.e. gaining fat and muscle, when there is little or even no food?

Cold increases metabolism in attempts to stay warm - shivering etc. Heat has little effect in human adults but in babies with brown fat and potentially other species you'd expect it to reduce basal metabolism.
