cava bio 204 s1.d48 3.17 Light and Photosynthesis

QuestionAnswer
[...] = (photo=light) + (synthesis=putting together) = putting carbons together using light energy. Photosynthesis = (photo=light) + (synthesis=putting together) = putting carbons together using light energy.
[...] is the visible portion of electromagnetic radiation. We can't see electromagnetic radiation above and below certain wavelengths, but all electromagnetic radiation is essentially the same be it visible light, or radio waves. Light is the visible portion of electromagnetic radiation. We can't see electromagnetic radiation above and below certain wavelengths, but all electromagnetic radiation is essentially the same be it visible light, or radio waves.
Green leaves have cells that contain an organelle called a [...]. Photosynthesis takes place in this organelle. Green leaves have cells that contain an organelle called a chloroplast. Photosynthesis takes place in this organelle.
The main sun-absorbing molecule used in photosynthesis is [...] . The main sun-absorbing molecule used in photosynthesis is chlorophyll .
At the center of chlorophyll is a [...] ion ([...]). That single atom is critical as it is involved in the absorption of visible light energy. At the center of chlorophyll is a magnesium ion (Mg). That single atom is critical as it is involved in the absorption of visible light energy.
Chlorophyll absorbs red and blue wavelengths of light, and reflects [...] wavelengths of light. Because chlorophyll does not use the [...] wavelengths and reflects them outward, you see leaves as [...] when that [...] light strikes your eyes. Chlorophyll absorbs red and blue wavelengths of light, and reflects green wavelengths of light. Because chlorophyll does not use the green wavelengths and reflects them outward, you see leaves as green when that green light strikes your eyes.
The first stage in photosynthesis is called the light-[...] reactions. The main purpose of light-[...] reactions is to generate electron carriers and some ATP. The first stage in photosynthesis is called the light-dependent reactions. The main purpose of light-dependent reactions is to generate electron carriers and some ATP.
Basically, light-dependent reactions are a type of [...] transport chain. Basically, light-dependent reactions are a type of electron transport chain.
Light-dependent reactions: Sunlight strikes a chlorophyll molecule. Electrons in the chlorophyll molecule become energized—or get excited—and move through a chain of proteins in the internal chloroplast [-s]. Light-dependent reactions: Sunlight strikes a chlorophyll molecule. Electrons in the chlorophyll molecule become energized—or get excited—and move through a chain of proteins in the internal chloroplast membranes.
Light-dependent reactions: As electrons travel through the electron transport chain, [...] ions are pumped across membranes, just like in cellular respiration. Their flow results in the production of ATP. Light-dependent reactions: As electrons travel through the electron transport chain, hydrogen ions are pumped across membranes, just like in cellular respiration. Their flow results in the production of ATP.
Cellular respiration involves NADH, while the light-dependent reactions of photosynthesis involve [...]. You can remember which in which by imagining that the P stands for plants (or photosynthesis). Cellular respiration involves NADH, while the light-dependent reactions of photosynthesis involve NADPH. You can remember which in which by imagining that the P stands for plants (or photosynthesis).
Light Dependent Reactions: The electrons that become part of NADPH have to come from somewhere. They come from a molecule of [...]. When [...] splits, oxygen gas forms and leaves the leaf. Light Dependent Reactions: The electrons that become part of NADPH have to come from somewhere. They come from a molecule of water. When water splits, oxygen gas forms and leaves the leaf.
Chlorophyll may be the main pigment in photosynthesis, but there are other pigments as well. We call them [...] pigments. They become visible when deciduous trees break down the pigments in their leaves. Chlorophyll may be the main pigment in photosynthesis, but there are other pigments as well. We call them accessory pigments. They become visible when deciduous trees break down the pigments in their leaves.
Different kinds of photosynthetic organisms have slightly different kinds of chlorophyll. Examples: green algae, red algae, brown algae, diatoms, and blue-green bacteria ([...]). Different kinds of photosynthetic organisms have slightly different kinds of chlorophyll. Examples: green algae, red algae, brown algae, diatoms, and blue-green bacteria (cyanobacteria).
Scientists give each variation of chlorophyll a different name, such as chlorophyll [...], chlorophyll [...], and so forth Scientists give each variation of chlorophyll a different name, such as chlorophyll A, chlorophyll B, and so forth
The first stage in photosynthesis is the light-dependent reactions and serves to generate the electron carrier [...]. Oxygen is also released. The first stage in photosynthesis is the light-dependent reactions and serves to generate the electron carrier NADPH. Oxygen is also released.
