Where is the energy in a plant cell?

Where is the energy in a plant cell?

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 happens to sugar that are made during photosynthesis?

The sugars produced by photosynthesis can be stored, transported throughout the tree, and converted into energy which is used to power all cellular processes. Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.

Which of the following directly provides the energy needed for cell functions *?

The energy required for cellular activities is provided directly by molecules of adenosine triphosphate (ATP). ATP is made of one adenosine molecule and three phosphate groups, called Pi for short. Each molecule of ATP stores a small quantity of chemical energy.

What molecule carries the chemical energy that cells use for their functions?

Adenosine 5′-triphosphate
Adenosine 5′-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups.

Why are plant cells important?

Plant Cells vs Animal Cells Their cells fulfil the same basic functions: taking nutrients from the environment, using those nutrients to make energy for the organism, and making new cells.

How is energy transformed in plant cells?

Photosynthesis. Plant cells obtain energy through a process called photosynthesis. This process uses solar energy to convert carbon dioxide and water into energy in the form of carbohydrates. Secondly, that energy is used to break down carbon dioxide and form glucose, the main energy molecule in plants.

What is used to make sugar in photosynthesis?

Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose.

Which sugar is produced during photosynthesis?

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.

How is energy released from a molecule of ATP?

When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).

Which of the following is the best description of photosynthesis?

Which of the following best describes photosynthesis? Photosynthesis converts radiant energy into chemical energy, Plants need sunlight, carbon dioxide, water, nutrients, and chlorophyll to complete photosynthesis, Photosynthesis produces carbohydrates.

What molecule provides the largest amount of ATP?


Question Answer
The breakdown of which of the following provides the largest number of ATP per molecule? lipids
Which of the following reactions provides the chemical energy for most cell functions? ATP – P –> ADP. The loss of a phosphate from ATP

What are the starting materials and products of photosynthesis and cellular respiration?

Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration. Cellular respiration makes carbon dioxide and water (and ATP), which are the starting products (together with sunlight) for photosynthesis.

Where does the energy from the light go in photosynthesis?

The energy that is generated from the light is passed from one P680 chlorophyll molecule to another until it reaches the reaction center (RC) of PSII. At the RC is a pair of P680 chlorophyll molecules. An electron in the chlorophyll molecules becomes excited as a result of a higher level of energy.

Why are the leaves important in the process of photosynthesis?

Leaves are essential for the well-being of plants. Most of the reactions involved in the process of photosynthesis take place in the leaves. The diagram below shows the cross section of a typical plant leaf.

Which is part of the transport chain in photosynthesis?

The water molecules labeled A in Figure 4.1 are going to the thylakoids to take part in which process? Which of the following is a reactant in photosynthesis? An electron transport chain that produces ATP is part of both the cellular respiration process and glycolysis. fermentation. photosynthesis. the Krebs cycle.

How are electrons released from chlorophyll in photosynthesis?

An electron in the chlorophyll molecules becomes excited as a result of a higher level of energy. The excited electron becomes unstable and is released. Another electron is released following the capture of another photon of light by the light harvesting complex and the transfer of energy to the reaction center.
