Systems& Photosynthesis Vs Cell Resp Flashcards
What is photosynthesis?
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose.
What is the primary function of cellular respiration?
The primary function of cellular respiration is to convert glucose and oxygen into energy (ATP), carbon dioxide, and water.
True or False: Photosynthesis occurs in the mitochondria of plant cells.
False: Photosynthesis occurs in the chloroplasts of plant cells.
What are the main inputs of photosynthesis?
The main inputs of photosynthesis are carbon dioxide, water, and light energy.
Fill in the blank: The equation for cellular respiration is ___ + ___ → ___ + ___ + energy (ATP).
glucose + oxygen → carbon dioxide + water + energy (ATP)
Which pigment is primarily responsible for capturing light energy in photosynthesis?
Chlorophyll.
What are the two main stages of photosynthesis?
The light-dependent reactions and the Calvin cycle (light-independent reactions).
Multiple choice: Which of the following is a product of photosynthesis? A) Glucose B) Oxygen C) Both A and B
C) Both A and B.
What is the role of oxygen in cellular respiration?
Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.
True or False: Both photosynthesis and cellular respiration are essential for life on Earth.
True.
What is the overall chemical equation for photosynthesis?
6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
Define autotrophs.
Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis.
Define heterotrophs.
Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy.
What is glycolysis?
Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.
Fill in the blank: The process of converting glucose into energy in the absence of oxygen is called ___ respiration.
anaerobic.
What is the main energy currency of the cell?
ATP (adenosine triphosphate).
Multiple choice: Which process occurs in the chloroplasts? A) Cellular respiration B) Photosynthesis C) Both A and B
B) Photosynthesis.
What is the byproduct of cellular respiration?
Carbon dioxide and water.
True or False: The Calvin cycle occurs in the chloroplast’s thylakoid membrane.
False: The Calvin cycle occurs in the stroma of the chloroplast.
What are the two types of cellular respiration?
Aerobic respiration and anaerobic respiration.
What is the role of light energy in photosynthesis?
Light energy is used to excite electrons in chlorophyll, initiating the process of converting light energy into chemical energy.
Fill in the blank: The light-dependent reactions of photosynthesis produce ___ and ___.
ATP and NADPH.
What is the significance of the electron transport chain in cellular respiration?
The electron transport chain produces the majority of ATP through oxidative phosphorylation.
Define the term ‘aerobic respiration’.
Aerobic respiration is the process of producing cellular energy in the presence of oxygen.
