Answer;
-The rate of the reaction;
The presence of an enzyme affects only the rate of the reaction.
Explanation;
-Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
-Additionally, the rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.
Answer:
1. Glycolysis: breaks down glucose into pyruvic acid and ATP
2. Electron transport chain: picks up hydrogens and produces ATP
3.Krebs cycle: produces carbon dioxide, water, and ATP
Explanation:
1. Glycolysis: It is a common process for both arerobic and anaerobic respiration in whcih one molecule of glucose (6-carbon) is converted into two molecules of pyruvic acid (3-Carbon). Net gain of 2 ATP during glycolysis and it occurs in cytoplasm of the cell.
2. Electron transport chain: It is the terminal step of aerobic respiration. It occurs on the inner membrane of the mitochondria where reduced coenzymes NADH and FADH₂ are oxidized and oxygen is final electron acceptor. ATPs are released.
3. Krebs cycle: Enzymatic reaction whcih occurs in the mitochondiarl matrix. In Krebs cycle, carbon dioxide, water, reduced coenzymes NADH and FADH₂and ATP are produced.
GABA is inhibitory, glutamate is excitatory
Answer:
Q1)Heart,Lungs,Arteries,Veins,Vessels
Q2)Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances.
