Through
the process of cellular respiration
, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
What converts energy in food to energy used by the cell?
Mitochondria
are important parts of our cells because they take food and make energy that the rest of the cell can use.
What organelle converts energy stored in food to energy the cell can use to live and function?
The mitochondria
are the organelles that convert various chemicals from food (glucose) into compounds that are more convenient for the cell to use,…
What converts food into energy in plant and animal cells?
Animal cells use
mitochondria
to convert food into energy, and plant cells use both chloroplasts and mitochondria to make energy from light, air, and water.
Which organelle converts the chemical energy stored in food into ATP that the cell can use and acts as the powerhouse of the cell?
Mitochondria
are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
How do we convert energy from food?
Food is the fuel for the body.
The mitochondria
are the converters; they convert the fuel into useable energy. When food is digested, or broken down into its smallest molecules and nutrients, and air is taken in, or inspired, the smallest molecules and nutrients cross into the bloodstream.
How does food break down into energy?
Glucose, found in the food animals eat, is broken down during
the process of cellular respiration
into an energy source called ATP. When excess ATP and glucose are present, the liver converts them into a molecule called glycogen, which is stored for later use.
What is the main source of energy for cells?
In fact,
the Sun
is the ultimate source of energy for almost all cells, because photosynthetic prokaryotes, algae, and plant cells harness solar energy and use it to make the complex organic food molecules that other cells rely on for the energy required to sustain growth, metabolism, and reproduction (Figure 1).
What is the main source of energy of the human body?
Carbohydrates
are the main energy source of the human diet. The metabolic disposal of dietary carbohydrates is direct oxidation in various tissues, glycogen synthesis (in liver and muscles), and hepatic de novo lipogenesis.
How is energy transferred from a plant to a person?
Energy is passed
between organisms through the food chain
. … Plants harvest their energy from the sun during photosynthesis. This energy can then be passed from one organism to another in the food chain. The organism that obtains energy from sunlight is called the producer.
Which two plant cell structures are responsible for storing energy from sunlight?
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.
Which substances are needed to make food in plants?
To perform photosynthesis, plants need three things:
carbon dioxide, water, and sunlight
. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food.
What helps support the plant cell and maintain its shape?
The large central vacuole is surrounded by its own membrane and contains water and dissolved substances. Its primary role is to maintain pressure against the inside of
the cell wall
, giving the cell shape and helping to support the plant. The cell wall is located outside the cell membrane.
Is the powerhouse of cell?
The mitochondria
, often labeled the powerhouse of the cell, are the organelle responsible for energy production within the cell. Playing an important role in cellular respiration, the mitochondria are the main location for ATP production.
What does the Golgi apparatus do?
The Golgi apparatus
transports and modifies proteins in eukaryotic cells
. How have scientists studied dynamic protein movements through the Golgi? The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell.
What is the Golgi apparatus function?
The Golgi apparatus, or Golgi complex, functions as
a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes
, the plasma membrane, or secretion. In addition, as noted earlier, glycolipids and sphingomyelin are synthesized within the Golgi.
