Chapter 32, Problem 2STP

Summary Introduction

Introduction:

Mitochondria are cell organelles that generate chemical energy required to power the cell's biochemical reactions. The chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Answer to Problem 2STP

Correct answer:

The correct answer is option (a) at number 1 there is Mitochondria.

Explanation of Solution

Explanation/justification for the correct answer:

Option (a) during everyday activities and light exercise, the mitochondria of muscle fibers produce ATP in a process called aerobic respiration. Aerobic respiration requires the presence of oxygen to break down food energy (usually glucose and fat) to generate ATP for muscle contractions.

The main organelle involved in respiration is the mitochondria. It's known as the powerhouse of the cell because 32 ATP is created from this organelle

Explanation for incorrect answer:

Option (b) at number 2 there is cytosomes. They are proteins that contain heme as their prosthetic group. Their principal function is the electron transport. They are firmly integrated in the inner membrane of the mitochondria.

Option (c) at number 3 there is lysosomes that regulate immune response by modulating cellular metabolism.

Option (d) at number 4 there are cell membranes that divide the interior of all cells from the outside environment and protects them.

Conclusion

The energy synthesized during cellular respiration is adenosine triphosphate (ATP). It is produced inside the mitochondria. Mitochondria are the energy-producing organelles of a cell. They do this function with the help of two cycles known as the Krebs cycle and electron transport chain.
