Through the process of
cellular respiration
, the energy in food is converted into energy that can be used by the body’s cells.
Where is most of the energy produced in cellular respiration?
Most of the ATP energy obtained from cellular respiration is produced
in the third and final stage, the electron transport chain
. In the electron transport chain, electrons are passed from one acceptor to the next, in a series of redox reactions.
What does the electron transport chain do in cellular respiration?
The primary task of the last stage of cellular respiration, the electron transport chain, is to
transfer energy from the electron carriers to even more ATP molecules
, the “batteries” which power work within the cell.
Which process converts energy into usable energy?
Cellular respiration
is the process of transforming chemical energy into forms usable by the cell or organism.
What processes use animals?
There are seven essential processes in common:
movement, respiration, sensitivity, growth, reproduction, excretion and nutrition
or MRS GREN.
What cellular process produces the most energy?
The Krebs cycle
takes place inside the mitochondria. The Krebs cycle produces the CO
2
that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).
Which of the following produces the most cellular energy?
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).
Which of the following processes produces the most ATP?
Explanation: The
electron transport chain
generates the most ATP out of all three major phases of cellular respiration. Glycolysis produces a net of 2 ATP per molecule of glucose.
Why does the electron transport chain produce the most ATP?
Electron transport chain produces an electrochemical gradient, which facilitates the synthesis of ATP by ATP synthase by chemiosmosis
.
How is the energy used to make ATP via the electron transport chain generated?
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis,
the energy stored in the gradient
is used to make ATP.
How is energy from glucose transferred to electron carriers?
In cellular respiration,
electrons from glucose move gradually through the electron transport chain towards oxygen
, passing to lower and lower energy states and releasing energy at each step. The goal of cellular respiration is to capture this energy in the form of ATP.
What process produces usable energy in cells quizlet?
Cellular Respiration
takes chemical energy stored in food and converts it into usable energy for the cell.
Which best summarizes cellular respiration?
Lesson Summary
Cellular respiration is
the process in which cells break down glucose, release the stored energy, and use it to make ATP
. The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.
What converts food into energy that is found in both 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.
How do animals get energy?
Animals get their energy
from the food they eat
. Animals depend on other living things for food. Some animals eat plants while others eat other animals. This passing of energy from the sun to plants to animals to other animals is called a food chain.
How does an animal cell get energy?
There are two ways cells get energy:
cellular respiration and fermentation
. During cellular respiration, cells use oxygen to break down food. During fermentation, food is broken down without oxygen. Cellular respiration releases more energy from food than fermentation.
How do animals get energy to move?
How do people and animals get energy to move? Animals, including humans, get
chemical energy from plants
. Even when animals eat meat, the chemical energy held in the meat came from the food that the animal ate. For example, cows get their energy by eating grass.
Which process produces the most ATP aerobic or anaerobic?
Summary.
Aerobic respiration
produces much more ATP than anaerobic respiration.
How do animal cells use nutrients to provide energy?
Animals obtain energy from the food they consume, using that energy to maintain body temperature and perform other metabolic functions.
Glucose, found in the food animals eat, is broken down during the process of cellular respiration into an energy source called ATP
.
What is the process of cellular respiration step by step?
The stages of cellular respiration include
glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation
.
Which step in cellular respiration produces the most ATP?
The stage that produces most of the ATP during cellular respiration is the
electron transport system (ETS) present in mitochondria
. The formation of ATP occurs by oxidative phosphorylation. Theoretically, 34 ATPs are produced in the ETS by the complete oxidation of a glucose molecule.
Which of the following is a form of cellular energy?
During cellular respiration, the energy formed in mitochondria is stored in the form of
ATP
which is also known as energy currency of the cell. It provides energy for all the life activities by its breakdown into ADP and Pi. ATP contains three phosphate group which has high energy bond.
Which of the following are produced during cellular respiration?
The products of cellular respiration are
carbon dioxide and water
. Carbon dioxide is transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled. ATP is generated in the process.
Which process makes the most ATP quizlet?
The
glycolysis stage
is responsible for producing most of the ATP during cellular respiration.
Which process produces the most ATP quizlet?
Most of the ATP in
cellular respiration
is produced by the process of chemiosmosis.
