Compare and contrast three metabolic pathways by choosing whether the statement applies to aerobic respiration. Check all that a
Arte-miy333 [17]

Answer:

The correct answer will be options

1. Process includes glycolysis.

2. Between 2 and 38 ATP are produced per molecule of glucose input .

3. Much or most of the ATP produced is produced by oxidative phosphorylation.

4. Process involves electron transport and chemiosmosis.

5.  End products are CO₂ and H₂O.

6. Process involves the Krebs cycle.

Explanation:

Cellular respiration is the oxidative process which involves the breakdown of food molecules like glucose, amino acids and fats to release heat and energy in the form of ATP.

In the presence of oxygen or aerobic respiration it undergoes four stages: glycolysis, link reaction, Krebs cycle and electron transport chain while in the anaerobic reaction it produces ethanol and carbon dioxide by the process of fermentation.

Each stage produces energy in the form of ATP molecules or co-enzymes NADH OR FADH₂ like glycolysis produces 2 ATP and link reaction, Krebs cycle produces NADH OR FADH₂ in addition to ATP. Each NADH produces 3 ATP while Each FADH₂ produces 2 ATP during electron transport chain.  So, ATP molecules are produced between 2 to 38 ATP molecules in each stage with large number during electron transport chain from these co-enzymes.

The waste products produced in the stages of cellular respiration are CO₂ molecules and H₂O which is also known as metabolic water.

How can scientific knowledge impact a decision about treating a disease outbreak?
andreyandreev [35.5K]

During any outbreak or whenever problems occur, there are always three major steps to take.

1. First, is the containment action. In this step, actions are taken to reduce or lessen the severity of the people affected. This aims in isolating the disease. In this step, scientific knowledge is used in making decision on what containment actions to take.

2. Second is the corrective action. This step focuses solely on formulating medicine to treat the disease. Once again scientific knowledge is used in creating those medicines.

3. Third is the preventive action. To prevent this disease outbreak from recurring, certain actions are made to ensure this does not happen again.

Explain how mutations cause cancer cells.
earnstyle [38]

Answer:

Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
