Question

The primary site of ATP synthesis in an animal cell is the:

A) nucleus
B) rough endoplasmic reticulum
C) Golgi
D) mitochondria

Answer 1

The mitochondria are the primary site of ATP synthesis in an animal cell, functioning as the powerhouses by producing the cellular energy carrier ATP through cellular respiration.

Step-by-step explanation:

The primary site of ATP synthesis in an animal cell is the mitochondria. These organelles, often referred to as the 'power plants' of the cell, are responsible for the production of ATP (adenosine triphosphate), which is the main energy carrier of the cell.

Cellular respiration occurs in the mitochondria, where glucose and oxygen are utilized to produce ATP, especially when the energy demand is high such as in muscle cells. It is here along the inner mitochondrial membrane that the electron transport chain and ATP synthesis take place.

Answer 2

The primary location for ATP synthesis in an animal cell is the mitochondria. These organelles are equipped with the necessary structures to convert organic compounds into ATP, providing essential energy for the cell to function. D is the correct answer.

Step-by-step explanation:

The primary site of ATP synthesis in an animal cell is the mitochondria (D). Mitochondria are known as the "power plants" of the cell because they are responsible for generating ATP, which is the cell's energy source.

This process occurs primarily through cellular respiration, which transforms energy from organic compounds into ATP molecules, crucial for various cell functions such as movement and cell division.

The mitochondrion has a unique structure that facilitates ATP production. It features two lipid bilayer membranes with a variety of molecules along the inner membrane working collectively to produce ATP. Muscle cells have a high concentration of mitochondria as they require a lot of energy for contraction.
