Answer the following question given this paragraph: Enzymes are involved in most of the chemical reactions that take place in organisms. Q: What substances, which serve as catalysts, are involved in most of the chemical reactions that take place in organisms? A:

OPTIONS:
- proteins
- vitamins
- carbohydrates
- enzymes

Answer: enzymes

Problem: OPTIONS:
- synthase
- mucosa
- sucrase
- amylase
Q: Answer the following question given this paragraph: The mouth is the first digestive organ that food enters. The sight, smell, or taste of food stimulates the release of digestive enzymes by salivary glands inside the mouth. The major salivary enzyme is amylase. It begins the chemical digestion of carbohydrates by breaking down starch into sugar. Q: The major salivary enzyme is called? A:
Answer: amylase

Problem:OPTIONS:
- ossicles
- cilia
- antlers
- spicules

Answer the following question given this paragraph: Some of the specialized cells grow short, sharp projections called spicules. Spicules make up the sponge's internal skeleton, or endoskeleton. The endoskeleton helps to support and protect the sponge. Q: What are the sharp projections that specialized cells grow called? A:
****
A: spicules

Answer the following question given this paragraph: Amphibians breathe with gills as larvae and with lungs as adults. They have a three-chambered heart and relatively complex nervous system. Q: What type of animals breathe with gills as larvae and with lungs as adults? A:
OPTIONS:
- insects
- reptiles
- mammals
- amphibians
amphibians

Answer the following question given this paragraph: every organism uses to power its metabolism. In brief, the energy of sunlight is captured and used to energize electrons, which are then stored in the covalent bonds of sugar molecules. How long lasting and stable are those covalent bonds? The energy extracted today by the burning of coal and petroleum products represents sunlight energy captured and stored by photosynthesis almost 200 million years ago. Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 8.2). Because they use light to manufacture their own food, they are called photoautotrophs (literally, "self-feeders using light"). Other organisms, such as animals, fungi, and most other bacteria, are termed heterotrophs ("other feeders"), because they must rely on the sugars produced by photosynthetic organisms for their energy needs. A third very interesting group of bacteria synthesize sugars, not by using sunlight's energy, but by extracting energy from inorganic chemical compounds; hence, they are referred to as chemoautotrophs. Q: Photoautotrophs use what energy source to self-manufacture their own food? A:
OPTIONS:
- water
- chlorophyll
- air
- light

Answer: light
