Cytochrome Pigments: Facts, Role & Function in Multilocular Fat Cells

AI Thread Summary
Cytochrome pigments are proteins found in the mitochondria that play a crucial role in cellular respiration and energy production. They contain heme groups that give them their color and are essential for the electron transport chain, which is vital for ATP synthesis. In multilocular fat cells, or brown adipose tissue, these pigments contribute to thermogenesis, a process that generates heat, particularly important for newborns and hibernating animals. The presence of cytochrome pigments in these cells aids in their ability to produce heat through metabolic processes, highlighting their role in energy expenditure and temperature regulation. Understanding the function of cytochromes in both mitochondria and chloroplasts can provide insights into their significance in various biological processes.

Hi,

Multilocular fat cells (brown adipose connective tissue) are pigmented by the cytochrome pigments in the mitochondria.

That is my textbook states, but I don't understand what are cytochrome pigments?

And why they found in mitochondria?

And why they pigment multilocular fat cells?

Could someone explain? Simply pleas!

Thanks in advance!

Newborns and hibernating animals need heat. There is something called thermogenesis within mitochondrial membranes.

Follow along those lines and you should be able to figure it out.

As for the color of cytochromes, look closely at cytochromes in chloroplasts.

Thread 'Did they discover another descendant of homo erectus?'

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...

Thread 'Warning of new opiod drug (nitazene) on the streets: Question re strength...'

Whenever these opiods are mentioned they usually mention that e.g. fentanyl is "50 times stronger than heroin" and "100 times stronger than morphine". Now it's nitazene which the public is told is everything from "much stronger than heroin" and "200 times stronger than fentany"! Do these numbers make sense at all? How do they arrive at them? Kill thousands of mice? En passant: nitazene have already been found in both Oxycontin pills and in street "heroin" here, so Naloxone is more...
