What is the main source of energy in photosynthesis?
the Sun
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.
Which process results in the most ATP energy produced?
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.
Which of the following is needed for aerobic respiration?
oxygen
Answer: Aerobic respiration requires the presence of oxygen.
What is the role of key organelles in energy transfer?
Light energy is converted into electrical energy. Which statement accurately describes the role of key organelles in energy transfer? Energy is captured and stored in the chloroplast and released in the mitochondria. Energy is captured and stored in the mitochondria and released in the chloroplast.
What is the main sources of energy made through photosynthesis for plants?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
When glucose is used as the energy source the largest amount of ATP is produced in?
When glucose is used as as energy source, the largest amount of ATP is generated by the portion of the entire respiratory process.
What forms of energy are produced by aerobic respiration?
In aerobic conditions, the process converts one molecule of glucose into two molecules of pyruvate (pyruvic acid), generating energy in the form of two net molecules of ATP.
What is the process by which energy is released from food molecules in the absence of oxygen called?
fermentation
The combined process of this pathway and glycolysis is called fermentation. Fermentation releases energy from food molecules by producing ATP in the absence of oxygen. During fermentation, cells convert NADH to NAD+ by passing high-energy electrons back to pyruvic acid.
Which organelles are responsible for energy transfer in the cell?
Mitochondria are organelles that are responsible for making adenosine triphosphate (ATP), the cell’s main energy-carrying molecule.
What is the organelle that provides the cell with energy?
Mitochondria
Mitochondria — often called the powerhouses of the cell — enable eukaryotes to make more efficient use of food sources than their prokaryotic counterparts. That’s because these organelles greatly expand the amount of membrane used for energy-generating electron transport chains.
How does the cell use energy to move substances?
To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism.
How is the energy stored in ATP used in active transport?
Active transport uses energy stored in ATP to fuel the transport. Active transport of small molecular-size material uses integral proteins in the cell membrane to move the material—these proteins are analogous to pumps. Some pumps, which carry out primary active transport, couple directly with ATP to drive their action.
How are molecules transported across the cell membrane?
Processes that cells use to move molecules across their membranes are: F. Exocytosis: (Exo – means to take out) Energy requiring process where a vacuole containing large molecules joins with the membrane, makes an opening, and squeezes the molecules out of the cell.
Which is energy requiring process in the amoeba?
E. Endocytosis: (Endo – means to bring in) Energy requiring process where cell membrane surrounds molecules, forming a pocket which becomes a vacuole in the cytoplasm. ( Animation) a) Phagocytosis: Membrane surrounds large particles, forms a pocket, then vacuole. This is how an amoeba or white blood cell feeds. ( Animation)
