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.

4vir4ik [10]

Answer:

This question is asking to fill in the blank spaces with the correct terms. The correct terms to the four blank spaces are:

1) GEL

2) DYE

3) DNA MARKER

4) LID

Explanation:

This question is describing the Gel electrophoresis technique which is used to separate DNA fragments using electric current. The DNA fragments of different sizes migrate through a GEL which serves as the matrix made from Agarose.

In order to physically see the samples that we put in the gel, we first have to add DYE to each sample of DNA. After loading the samples to be separated, a substance made up of DNA fragments of known sizes referred to as DNA MARKER, which acts as the standard curve in a tube is used.

Before running the gel, it's important to make sure that there is LID covering the gel in the gel rig. This will make sure that the electrical current runs through the gel and the gel stays cool.

What does mean to say the average daytime relative humidity of. Particular city is 31 percent%
victus00 [196]

It practically means that the air in the city has less than a third of water vapor it could contain under the same circumstances.

Relative humidity is the ratio of water vapor that the air contains to the maximum amount it could carry at the same temperature.

When the humidity is high, the water vapor in the air is a variety more, and vice versa.
