In which organelle does photosynthesis take place?
Chloroplast
TRUE OR FALSE?
In exothermic reactions, enzymes speed up chemical reactions by lowering the overall energy released in the chemical reaction.
FALSE
What is the main energy molecule produced by cell respiration?
ATP
What gas is a byproduct of photosynthesis?
Oxygen
What type of energy is converted into chemical energy during photosynthesis?
Light energy
What part of the chloroplast contains chlorophyll?
Thylakoid membrane
What type of biological molecule are enzymes?
Proteins
What molecule is the final electron acceptor in the electron transport chain during cell respiration?
Oxygen
Through which structures do plants exchange gases with the environment?
Stomata
Which pigment primarily absorbs light for photosynthesis?
Chlorophyll
What is the main purpose of the inner membrane of the chloroplast?
It controls the passage of materials and contains proteins important for photosynthesis.
Which enzyme is responsible for the formation of ATP during the Electron Transport Chain(ETC) phase?
ATP Synthase
In which part of the mitochondria does the electron transport chain occur?
Inner mitochondrial membrane
Why do leaves have a large surface area in relation to gas exchange?
To maximize the absorption of carbon dioxide and the release of oxygen.
What are the two main stages of photosynthesis?
Light-dependent reactions and the Calvin cycle
Where in the chloroplast do the light-dependent reactions happen?
Thylakoid membrane
How do enzymes help control energy in photosynthesis?
Enzymes speed up and guide the steps in photosynthesis, making sure the energy is used properly and the process runs smoothly.
What is the net gain of ATP molecules from one molecule of glucose during aerobic respiration?
36-38 ATP molecules
What is the process by which carbon dioxide enters plant cells and oxygen exits?
Diffusion
What is the first law of thermodynamics?
energy cannot be created or destroyed, but it can be converted from one form to another.
