Question

Which statement best describes how the organelles labeled Y and Z work together to maintain homeostasis in the cell?

A. Organelle Y creates sugar and oxygen, which organelle Z uses to create energy.
B. Organelle Z creates sugar and oxygen, which organelle Y uses to create energy.
C. Organelle Y creates protein for food, which organelle Z uses to create energy.
D. Organelle Z creates protein for food, which organelle Y uses to create energy.

Answer 1

Statement A best describes how the organelles labeled Y and Z work together to maintain homeostasis in the cell.

Based on the image and the labels of the organelles, the correct statement describing how Y and Z work together to maintain homeostasis is:

A. Organelle Y creates sugar and oxygen, which organelle Z uses to create energy.

Here's why:

Organelle Y is labeled as the chloroplast. Chloroplasts are responsible for photosynthesis, a process that uses sunlight, water, and carbon dioxide to produce sugar (glucose) and oxygen.

Organelle Z is labeled as the mitochondrion. Mitochondria are the powerhouses of the cell and are responsible for cellular respiration, a process that uses glucose and oxygen to produce ATP (adenosine triphosphate), the main energy currency of the cell.

Therefore, the sugar and oxygen produced by Y (chloroplast) are directly used by Z (mitochondrion) to create ATP, which helps maintain various cellular functions and ultimately contributes to homeostasis.

The other options are incorrect because:

B: While mitochondria can use other molecules besides glucose for energy production, sugar (glucose) is the primary fuel source for cellular respiration.

C and D: Protein is not directly used by mitochondria for energy production. While proteins are essential for various cellular processes, they are not a primary fuel source for cellular respiration.

Answer 2

A. Organelle Y creates sugar and oxygen, which organelle Z uses to create energy. Organelle Y creates sugar and oxygen, which organelle Z uses to create energy.

Step-by-step explanation:

The correct answer is A. Organelle Y creates sugar and oxygen, which organelle Z uses to create energy.

Organelle Y refers to the chloroplasts, which are responsible for photosynthesis. During photosynthesis, chloroplasts capture sunlight energy and convert it into sugar (glucose) and oxygen as a byproduct.

Organelle Z refers to the mitochondria, which are responsible for cellular respiration. Mitochondria use glucose and oxygen to produce ATP, the cell's main energy carrier. The process of cellular respiration occurs in the mitochondria and requires oxygen and glucose as inputs.
