Photosynthesis

The light reactions of photosynthesis take place in the
1. stroma
2. thylakoids
3. mitochondria
4. nucleus
The light-independent reactions of photosynthesis take place in the
1. stroma
2. thylakoids
3. mitochondria
4. nucleus
Photosynthesis takes place in which organelle?
1. the nucleus
2. the mitochondrion
3. the vacuole
4. the endoplasmic reticulum
5. the ribosome
6. the chloroplast
Photosynthesis takes place in the organelle labeled
What two energy carrying molecules are produced by the light reactions of photosynthesis?
1. NADP⁺ and ADP
2. NADP⁺ and NADPH
3. NADPH and ATP
4. ADP and ATP
5. NADP⁺ and ATP
Energy from sunlight is captured by the pigment
Structures known as grana are stacks of
Which of the following equations correctly sums up the overall process of photosynthesis?
Carbon dioxide is required for which of the following processes in photosynthesis
1. the Calvin cycle
2. the splitting of water
3. the production of ATP
4. the absorption of water
A granum has been given the label number
Which numered label indicates the region where the light-independent reactions take place?
The light dependent reactions take place in the membrane labeled by the number
The splitting of water molecules is essential for the photosynthetic production of
1. carbon dioxide
2. sunlight
3. ATP and NADPH
4. chlorophyll
A plant is provided adequate carbon dioxide and water, but no light. In this plant
1. photosynthesis will not occur.
2. photosynthesis will occur more slowly than in the light.
3. ATP and NADPH will be stored until sunlight becomes available.
4. the light independent reactions will continue to produce glucose
Plant contain mitochondria in addition to chloroplasts. This is necessary because
1. plants must make use of respiration when light is not available.
2. the ATP needed for photosynthesis is produced in the mitochondria.
3. the mitochondria produce proteins essential to photosynthesis
4. the mitochondria are how carbon dioxide enters the plant cell
All energy conversions, even in living cells, are very inefficient. Life can survive despite this inefficiency because
1. cells require very little energy
2. the sun continually provides new energy
3. wastes are recycled
4. water is an abundant element on Earth
