The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).
What to organelles are directly involved in energy transformations in the cell?
Therefore the two cell organelles which are involved in energy transformation reactions are chloroplast and mitochondria.
Which organelle is involved for energy transformation of light energy to chemical energy?
Mitochondria are the working organelles that keep the cell full of energy. In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose.
What organelle performs these energy conversions in all eukaryotic cells?
Within eukaryotic cells, mitochondria function somewhat like batteries, because they convert energy from one form to another: food nutrients to ATP.
How is energy converted in the cell?
Cells do not use the energy from oxidation reactions as soon as it is released. Instead, they convert it into small, energy-rich molecules such as ATP and nicotinamide adenine dinucleotide (NADH), which can be used throughout the cell to power metabolism and construct new cellular components.
Which pigment transforms light energy into chemical energy most directly?
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars).
How does light energy get converted into chemical energy?
Light energy is converted to chemical energy when a photochemically excited special chlorophyll molecule of the photosynthetic reaction center loses an electron, undergoing an oxidation reaction.
Which organelle changes chemical energy into a form that is usable by the cell?
(A) The mitochondrion converts energy from chemical fuels.
What two organelles are involved in making converting energy?
Two types of membranous organelles that specialize in energy conversion are the chloroplasts and mitochondria. Chloroplasts use solar energy to make carbohydrates by using photosynthesis. Mitochondria break down carbohydrates to produce adenosine triphosphate (ATP).
Which organelle distributes substances within the cell?
The Golgi apparatus is a set of flattened, membrane-bound sacs that serve as the packaging and distribution center of the cell.
What does Golgi apparatus do?
A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
