Answer:
POLYMER
Explanation:
Small molecules called monomers combine together in a process called polymerization to form a larger molecule called POLYMER. A polymer is a large molecule consisting of long chains of small molecules (monomers) chemically bonded together.
The process of polymerization often involves the loss of water molecule. These polymers (macromolecules) are important for the optimal functioning of living systems, or the production of important substances.
Answer:
Letter a. Yes, yeasts can exist in an oxygen-poor environment.
Explanation:
Mitochondria are an organelle that we can find in the majority of eukaryotic cells. Mitochondria help in produces the energetical molecule of ATP. We start with one molecule of glucose that passes through a process called glycolysis to convert glucose into pyruvate. This pyruvate molecule can follow two pathways: when oxygen is available the pyruvate enter into the Krebs cycle and proceeds to the respiratory chain in the mitochondria, when oxygen is not present, pyruvate pass into another pathway, one is the alcoholic fermentation producing ethanol and dioxide of carbon.
As yeast are a eukaryotic organism, they have mitochondria and can grow in the presence of oxygen. When oxygen is absent yeast can grow using the fermentation pathway producing alcohol.
