[43] Cold-Induced Thermogenesis Flashcards
What is Cold-Induced Thermogenesis?
The process by which the body produces heat in response to exposure to cold.
What triggers Cold-Induced Thermogenesis?
Exposure to cold temperatures.
Which type of adipose tissue plays a major role in Cold-Induced Thermogenesis?
Brown Adipose Tissue (BAT)
How does Brown Adipose Tissue (BAT) contribute to Cold-Induced Thermogenesis?
It burns fat to produce heat when the body is exposed to cold.
What is BAT?
BAT stands for Brown Adipose Tissue.
Which protein plays a crucial role in Cold-Induced Thermogenesis?
Uncoupling Protein 1 (UCP1).
What is UCP1?
UCP1 stands for Uncoupling Protein 1.
What is the function of UCP1 in Cold-Induced Thermogenesis?
UCP1 uncouples the respiratory chain in mitochondria, leading to heat production instead of ATP synthesis.
How does the body signal for Cold-Induced Thermogenesis?
The nervous system detects cold and sends signals to brown adipose tissue to start burning fat for heat.
Can Cold-Induced Thermogenesis contribute to weight loss?
Yes, by increasing energy expenditure through heat production.
What impact does Cold-Induced Thermogenesis have on the metabolic rate?
It increases the metabolic rate.
What is the metabolic rate?
The rate at which the body uses energy or burns calories.
Is Cold-Induced Thermogenesis solely a human response to cold?
No, it is a common response across many animals, especially those in cold environments.
How does Cold-Induced Thermogenesis affect body temperature?
It helps to maintain a stable body temperature during cold exposure.
Is Cold-Induced Thermogenesis a voluntary or involuntary process?
It is an involuntary process.
