<h2>Fatty acid oxidation </h2>
Explanation:
- Activation of fatty acids (palmitate) occurs in the cytoplasm where fatty acids are activated to fatty acyl CoA, reaction catalysed by an enzyme called fatty acyl CoA synthetase
- A specialized carnitine carrier system catalyze transportation of activated fatty acid from cytoplasm to matrix of mitochondria, where carnitine system consists of three proteins:
- Carnitine acyl transferase I located in outer membrane of mitochondria catalyze transfer of carnitine to fatty acyl CoA and produce fatty acyl carnitine
- Carnitine translocase facilitate passive diffusion of fatty acyl carnitine from inter membrane space to matrix located in inner membrane
- Carnitine acyl transferase III located in inner mitochondrial membrane at matrix phase catalyze transfer of CoA to fatty acyl carnitine and regenerate fatty acyl CoA
Hence, the cytosolic and mitochondrial pools of CoA are thus kept separate, and no radioactive CoA from the cytosolic pool enters the mitochondria
<span>Protists obtain food in 3 ways. They produce their own
organic molecules, ingest, and absorb.
Ingestive protists ingest food, or engulf bacteria. These protists extend their cell wall and cell membrane forming a
food vacuole around the food item. Inside the food vacuole, enzymes digest the
food. Absorptive protists on the other hand, absorb food molecules across their cell membrane which takes place
through diffusion. Absorptive protists play a key role in decomposition. They are
considered as important decomposers. Major producers like photosynthetic protists use light energy to manufacture their own food.</span>
Answer:
I would say all three describes the Sahara. Dry, thin soil sounds like sand, which is the soil in the Sahara Desert. This ecosystem definitely has a small amount of rain; that's what defines a desert. Along with that, the Sahara is also very diverse, inhabited by many organisms, from bugs, snakes, and other reptiles to rabbits, jackals, foxes, and even camels. Hope this helps!
