Answer:
The correct answer is option C- "oxidize, reduce".
Explanation:
Fermentation is a process analogous to cellular respiration and, just like the latter, it involves oxidization and reduction of molecules with the final purpose of producing energy. During the process of fermentation nicotinamide adenine dinucleotide + hydrogen (NADH) is oxidized to its original form of NAD with a plus charge; while other organic molecules such as piruvate are reduced.
<span> Gravitational forces are only attractive but electromagnetic forces are both attractive and repulsive.</span> Because magnetic force has negative and positive charges, it can be both attractive and repulsive. Gravity affects objects at a distance, but the attraction weakens as the objects get farther apart.
Answer:
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 1). Because they use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).
Answer:
The diagram represents a plant leaf cell and two different molecules used in the process of glucose synthesis. ... The arrows in the diagram indicate the movement of molecules of oxygen and water into the cell.
Explanation:
Answer:
Conformational change
Explanation:
To understand how allosteroic enzymes work, one has to know how enzymatic reactions are executed. See below:
A ⇒ B
A: Represents the substrate of the reaction
B: Represents the product of the reaction
E: Represents the enzyme that catalyzes this reaction
Enzymatic reactions normally are controlled by the amount of substrate (A) or product (B) present in the environment. One way enzymes can control the reaction rate is through the presence of allosteric sites. These are specialized regions capable of binding molecules called effectors, causing a conformational change in the enzyme which leads to either acceleration or stalling of the reaction (depending on the specific enzyme and/or effector under study). Both substrates (A) and products (B) may act as effectors, resulting in, respectively, acceleration and slowing of the reaction.
