Which group of organelles is directly responsible for the production and processing of proteins within a cell?

Which group of organelles is directly responsible for the production and processing of proteins within a cell?

ribosomes

Which organelles are directly responsible for the production and cycling of energy molecules at the cellular level?

Mitochondria. Mitochondria (singular = mitochondrion) are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell’s main energy-carrying molecule. The formation of ATP from the breakdown of glucose is known as cellular respiration.

Which organelle is responsible for producing?

mitochondria

What organelle is responsible for producing new protein molecules?

Which organelles are involved in the production of proteins?

The endoplasmic reticulum (ER) is a membranous organelle that shares part of its membrane with that of the nucleus. Some portions of the ER, known as the rough ER, are studded with ribosomes and are involved with protein manufacture.

What are the 3 organelles?

Three organelles contain DNA: the nucleus, mitochondria and chloroplasts.

How does a plant cell function?

Plant cells are the building blocks of plants. Photosynthesis is the major function performed by plant cells. Photosynthesis occurs in the chloroplasts of the plant cell. It is the process of preparing food by the plants, by utilizing sunlight, carbon dioxide and water.

What is the structure and function of a plant cell?

Plant cells are differentiated from the cells of other organisms by their cell walls, chloroplasts, and central vacuole. Chloroplasts are organelles that are crucial for plant cell function. These are the structures that carry out photosynthesis, using the energy from the sun to produce glucose.

What is plant cell and its function?

Plant cells contain chloroplasts. Unlike animal cells, plant cells can harness the energy of the Sun, store it in the chemical bonds of sugar and later use this energy. The organelle which is responsible for this is the chloroplast.

What are the three functions of Golgi apparatus?

A major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.

What is the structure and function of chloroplasts?

Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells, including the synthesis of fatty acids, membrane lipids.

What is the best organelle?

Mitochondria

Can humans live without mitochondria?

You can’t survive without mitochondria, the organelles that power most human cells. Mitochondria are the descendants of bacteria that settled down inside primordial eukaryotic cells, eventually becoming the power plants for their new hosts.

How do prokaryotes survive without mitochondria?

Prokaryotes, on the other hand, don’t have mitochondria for energy production, so they must rely on their immediate environment to obtain usable energy. Prokaryotes generally use electron transport chains in their plasma membranes to provide much of their energy.

Which cells do not have a mitochondria?

The number of mitochondria per cell varies widely; for example, in humans, erythrocytes (red blood cells) do not contain any mitochondria, whereas liver cells and muscle cells may contain hundreds or even thousands. The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species.
