Marco has experienced extreme fatigue (tiredness) lately. He eats three balanced meals each day and exercises 2-3 times per week

Kisachek [45]

Given the symptoms shown by Marcos, we can infer that the organelle that may be causing his problems is the mitochondria.

The mitochondria are one of the most famous and important organelle within a cell. Found in most eukaryotic cells, they are the organelle responsible for most of the energy production of a cell, and throughout the cells of the body, they become responsible for the energy production of the organism. This is the origin of its famous "Powerhouse of the cell" title. Mitochondria produce energy in the form of ATP.

ATP is a molecular compound necessary for most of the reactions that take place in a cell. It is so common as a requirement for any cellular activity that ATP is known as the "molecular currency". Marcos is said to be experiencing chronic fatigue, which is a symptom of mitochondrial disease. When the mitochondria of an organism's cells are not functioning as they should be, the cells do not have the energy needed to perform basic functions.

In reaction to this, the body sends signals to the brain to go to sleep, which minimizes energy consumption by slowing down the metabolic processes which require ATP and thus gives the body time to produce more energy. For these reasons, we can conclude that the fatigue and problems Marcos is experiencing are due to mitochondrial disease.

In which step of protein synthesis does the rRNA make protein?

Inessa [10]

Answer:

Translation is the second part of the central dogma of molecular biology: RNA → Protein. It is the process in which the genetic code in mRNA is read to make a protein. Translation is illustrated in the diagram below. After mRNA leaves the nucleus, it moves to a ribosome, which consists of rRNA and proteins.

Explanation:

Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.

Answer:

The correct option is b

Explanation:

Phospholipids are lipids that contains a phosphate group, which forms the "head" of the molecule and is hydrophilic (water loving). The "tail" of phospholipids is made of two fatty acids which are hydrophobic (water fearing). The phospholipid in the cell membrane acts as a selectively permeable barrier that regulates what goes in and out of the cell thereby protecting the cell from some external molecules and ions.
