Cellular respiration
releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.
What is the process called that releases energy from glucose?
The source of the energy required to regenerate ATP is the chemical energy stored in food (e.g. glucose). The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP.
What is the process of using oxygen and glucose to produce energy called?
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.
Where is this energy stored in glucose?
Energy is stored in
the chemical bonds of the glucose molecules
.
What type of respiration requires oxygen?
Aerobic respiration
is a specific type of cellular respiration, in which oxygen (O
2
) is required to create ATP.
What are the 10 steps in glycolysis?
- Step 1: Hexokinase. …

- Step 8: Phosphoglycerate Mutase.
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 process does not release energy from glucose?
Explanation:
The process of photosynthesis
is not associated with the release of energy from the glucose molecule. This process is performed by the plant system to form chemical energy by using light energy which can later be stored in carbohydrate molecules.
What kind of energy does glucose contain?
A molecule of glucose, which has the chemical formula C
6
H
12
O
6
, carries a packet of
chemical energy
just the right size for transport and uptake by cells. In your body, glucose is the “deliverable” form of energy, carried in your blood through capillaries to each of your 100 trillion cells.
What type of energy does glucose contain?
Explanation: It’s
chemical energy
because when glucose is broken down into ATP or adenosine triphosphate it releases chemical energy into the cells that use it for energy.
Where is the sun’s energy stored in glucose?
This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules. Inside the plant cell are small organelles called
chloroplasts
, which store the energy of sunlight.
What is the presence and absence of oxygen?
The Presence of Oxygen
There are two types of cellular respiration (see Cellular Respiration concept): aerobic and
anaerobic
. One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic). Both begin with glycolysis – the splitting of glucose.
What is the name of respiration that occurs in the absence of oxygen?
Anaerobic respiration
does not need oxygen (unlike aerobic respiration). It is the release of a relatively small amount of energy in cells by the breakdown of food substances in the absence of oxygen.
What type of respiration do humans have?
Respiration process that occurs in the presence of oxygen is called
aerobic respiration
, generally seen among humans. But in certain organisms like bacteria and algae, respiration occurs in the absence of oxygen, called anaerobic respiration.
What is the most important step in glycolysis?
The most important regulatory step of glycolysis is
the phosphofructokinase reaction
. Phosphofructokinase is regulated by the energy charge of the cell—that is, the fraction of the adenosine nucleotides of the cell that contain high‐energy bonds.
What is the first step in glycolysis?
Step 1:
Glucose is phosphorylated by the enzyme hexokinase to form glucose 6- phosphate
. Glucose gains energy by being phosphorylated at the expense of one ATP. Step 2: Glucose 6-phosphate is converted into its isomer, fructose 6-phosphate, by an isomerase enzyme.
