Question

Maximum number of mitochondria are found in:
A. Chaos chaos
B. Typanosoma
C. Oocyte
D. Oocyte of sea urchin

Answer 1

Hint: Mitochondria are called the powerhouse of the cell. They are membrane bound cell organelles that help in generating energy.

Complete step by step answer:
Chaos chaos is a genus of single cell amoeboid organisms.
The number of mitochondria in a cell vary widely.
The red blood cells have no mitochondria.
The mitochondria are found in most eukaryotic organisms.
20-24 mitochondria are present in sperms.
300-400 mitochondria are present in kidney cells.
500-1000 mitochondria in liver cells
50000 mitochondria in giant amoeba called chaos chaos.
The chemical energy which is produced by the mitochondria is stored in ATP.
The mitochondria are also involved in signaling, cell death, differentiation as well as in the cell growth and cell cycle.
Mitochondria have an inner and outer membrane. The outer membrane has proteins called porins which helps in movement of ions into and out of mitochondria.
The matrix is the space within the inner membrane of the mitochondria.
The matrix has enzymes of krebs, and fatty acid cycles.
The inner membrane has ATP synthase which generates ATP in the matrix.
To increase the surface area for energy production, the inner membrane is arranged into a cristae.
So the correct answer is chaos chaos.

So the correct answer is A.

Note: The mitochondrion is the site of ATP synthesis for the cell. The mitochondria provide the energy for oocyte maturation, fertilization and formation of embryos. The mitochondrion helps in maintaining the intracellular environment:
1. The mitochondria store caspases for triggering apoptosis.
2. Store calcium helps in calcium homeostasis.
