UCP1 expression is increased specifically in adipose tissue. During glucagon signaling in adipose, what would be the fuel source

for the adipose cell and what happens to the fuel normally and then with irisin signaling? What do you expect would happen to the level of oxygen consumption, electron transport, and ATP production PER FATTY ACID in adipose cells when UCP1 expression increases?

Answer:Brown adipose tissue (BAT) mitochondria are distinct from their counterparts in other tissues in that ATP production is not their primary physiologic role. BAT mitochondria are equipped with a specialized protein known as uncoupling protein 1 (UCP1). UCP1 short–circuits the electron transport chain, allowing mitochondrial membrane potential to be transduced to heat, making BAT a tissue capable of altering energy expenditure and fuel metabolism in mammals without increasing physical activity.

The recent discovery that adult humans have metabolically active BAT has rekindled an interest in this intriguing tissue, with the overarching aim of manipulating BAT function to augment energy expenditure as a countermeasure for obesity and the metabolic abnormalities it incurs. Subsequently, there has been heightened interest in quantifying BAT function and more specifically, determining UCP1-mediated thermogenesis in BAT specimens – including in those obtained from humans.

In this article, BAT mitochondrial bioenergetics will be described and compared with more conventional mitochondria in other tissues. The biochemical methods typically used to quantify BAT mitochondrial function will also be discussed in terms of their specificity for assaying UCP1 mediated thermogenesis. Finally, recent data concerning BAT UCP1 function in humans will be described and discussed.

Answer:

The 2 ways abiotic factors affect biotic factors are as follows:

  1. An alligator submerges itself under water to stay cool in the summer.
  2. A naked mole rat creates burrows underground.

Explanation:

Abiotic Factors:

All non-living factors that is present or influences an ecosystem. Abiotic factors determine the dynamics of an ecosystem such as the terrain, the atmosphere as well as the inhabitant flora and fauna. Water, sunlight, oxygen, temperature, and soil are all abiotic factors.

Biotic Factors:

All living factors in an ecosystem i.e. the plants and animals.

Lets analyze all the options:

  • A bird picking food out of an alligator's teeth is an interaction between 2 biotic factors, the bird and the alligator or in another case, the bird and the food.
  • Water being oxygenated is an interaction between 2 abiotic factors: water and oxygen.

A ____ is the underlying combination of genetic material present (but outwardly invisible) in an organism.
Alex

Answer:

D (Genotype)

Explanation:

A genotype is the genetic make up of an organism i.e. what the genetic material

of an organism constitutes. Genotype describes the set of genes contained in an organism's genome. According to Mendel, an organism receives two forms of genes called ALLELE for a trait, one from each parent. The genotype of a specific gene coding for a trait is represented by each pair of allele for that trait.

Although the genotype of an organism is outwardly invisible i.e. cannot be seen, but it determines the phenotype of that organism i.e. the outward appearance. For example, if a plant receives T and T alleles coding for tallness, from each parent. The genotype of that plant for the specific height trait will be (TT). Hence, the TT genotype although invisible but controls the tallness of the plant.
