What is the purpose of the folded inner membrane in mitochondria
Andrei [34K]

Answer:

Increase the membrane surface area which creates more work space

Explanation:

Mitochondrion (Plural-mitochondria) is referred to as the powerhouse the the cell because it is the site of ATP (energy rich compound) synthesis in the cell. Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes; the outer membrane, which sheds the organnelle and contains it like a skin and the inner membrane, which folds over many times and creates a layered invagination called CRISTAE.

The folding of the inner membrane increases the membrane surface area inside the organnelle. Since many of the chemical reactions e.g. Cellular respiration (ETC and Chemiosmosis) occur in the inner membrane, the increased surface area creates more space for the reactions to occur.

It is just reasonable that the more the space, the more the work that can be done.

That the allele that gives human red blood cells increased resistance to malarial parasites also reduces the amount of oxygen th
ella [17]

Answer:

A (Genotype)

Explanation:

All organisms possess genetic material which contains information required for certain functions/traits. This genetic material is stored as DNA and contains certain segment that encodes functional products (proteins) called GENE. The make-up of the genes responsible for a particular characteristics in an organism is called the GENOTYPE. Genes occur in variant forms called ALLELES, which are inherited from each parent.

These alleles are responsible for the varying expression of a particular trait e.g. allele T can be responsible for Tallness while the variant form, allele t can be responsible for shortness. In this example, we can see that height is the trait here but the different alleles encode varying expression of it. The combination of the alleles received by both parents, which collectively determines the trait to be expressed is the GENOTYPE.

N.B: The genotype refers to the physically invisible genes not the expressed trait itself, which is the phenotype.

In this case, an allele (gene variant) is responsible for the resistance of Red Blood cells and regulates oxygen carried by them. The phenotype is the resistance that the RBC's possess and its reduced ability to carry oxygen but the combination of alleles responsible for that trait is the GENOTYPE.

Why is atp use in cells analogous to the use of currency in society?
tamaranim1 [39]
ATP is the resource by which the cell gets everything done.  ATP is spent in a similar way as money is.  ATP is used for its energy to help the cell run efficiently.  It earns ATP through energy creation, then has to spend it to perform other vital functions.
