Flashcards covering the primary functions of key cellular organelles and biological molecules.
What is the primary function of mitochondria in a cell?
Mitochondria are responsible for producing ATP (adenosine triphosphate), the main energy currency of the cell. Often referred to as the 'powerhouses' of the cell, mitochondria generate most of the cell's supply of ATP through cellular respiration.
The process of {{c1::ATP production}} occurs primarily in the mitochondria.
Mitochondria are the site of cellular respiration, which generates ATP.
What is the main role of ribosomes in a cell?
Ribosomes are responsible for synthesizing proteins. Ribosomes translate messenger RNA (mRNA) sequences into amino acid chains, forming proteins.
Ribosomes are the cellular machinery responsible for {{c1::protein synthesis}}.
Ribosomes read genetic instructions carried by mRNA to build proteins.
Where is the cell's DNA primarily stored?
The nucleus is the primary storage location for the cell's DNA. The nucleus contains the cell's genetic material (DNA) organized into chromosomes.
The {{c1::nucleus}} serves as the central repository for the cell's genetic information in the form of DNA.
The nucleus houses the chromosomes, which are made of DNA.
What is the function of chlorophyll in plants?
Chlorophyll's primary role is to absorb light energy, particularly in the red and blue wavelengths of the visible spectrum. This absorbed light energy is crucial for driving the process of photosynthesis.
The pigment {{c1::chlorophyll}} is essential for capturing light energy during photosynthesis.
Chlorophyll molecules within chloroplasts absorb photons of light.
What are the main products of photosynthesis?
Photosynthesis produces glucose (a sugar) and oxygen. Glucose serves as food for the plant, and oxygen is released as a byproduct.
During {{c1::photosynthesis}}, plants convert light energy, water, and carbon dioxide into glucose and oxygen.
This process is vital for life on Earth, providing food and oxygen.
What molecule is often called the 'energy currency' of the cell, primarily produced by mitochondria?
ATP (adenosine triphosphate) is the energy currency of the cell. Mitochondria generate ATP through cellular respiration to power cellular activities.
What cellular component is responsible for translating genetic code into proteins?
Ribosomes are responsible for protein synthesis. They read mRNA sequences and assemble amino acids into polypeptide chains.
Which organelle contains the majority of a eukaryotic cell's genetic material (DNA)?
The nucleus contains the cell's DNA. The DNA is organized into chromosomes within the nuclear envelope.
What is the green pigment found in plants that absorbs light energy for photosynthesis?
Chlorophyll is the green pigment that absorbs light energy. It is located in the chloroplasts and is essential for capturing photons.
What are the two main outputs of the photosynthetic process?
The main products of photosynthesis are glucose and oxygen. Glucose is used by the plant for energy, and oxygen is released into the atmosphere.
