Respiration is an important process. Discuss respiration and explain its importance to an organism. In your answer, be sure to: • identify the organelle where this process occurs [1]

Correct Answer
mitochondria

Explanation
Mitochondria are the organelles where respiration occurs. Respiration is a vital process for organisms as it is responsible for producing energy in the form of ATP. It involves the breakdown of glucose molecules through a series of chemical reactions, ultimately releasing energy that is used for various cellular activities. Without respiration, organisms would not be able to carry out essential functions such as growth, reproduction, and movement. Thus, the presence of mitochondria and the occurrence of respiration are crucial for the survival and functioning of organisms.

Respiration is an important process. Discuss respiration and explain its importance to an organism. In your answer, be sure to: • identify one energy-rich molecule that is produced by this process [1]

Correct Answer
ATP

Explanation
Respiration is the process by which organisms convert glucose and oxygen into carbon dioxide, water, and energy. ATP (adenosine triphosphate) is an energy-rich molecule produced during respiration. ATP serves as the primary source of energy for cellular activities in organisms. It provides the necessary energy for muscle contractions, nerve impulses, active transport across cell membranes, and synthesis of molecules. Without ATP, essential biological processes would not occur, and organisms would not be able to perform vital functions necessary for survival and growth.

Respiration is an important process. Discuss respiration and explain its importance to an organism. In your answer, be sure to: • identify 1 of the 2 raw materials necessary for this process [ 1 ] (only enter one or it'll mark you wrong).

Correct Answer
glucose
o2
oxygen
O2

Explanation
Respiration is the process by which organisms convert glucose and oxygen into energy, carbon dioxide, and water. Glucose is one of the raw materials necessary for respiration as it provides the fuel for the process. Oxygen, represented as O2, is the other essential raw material required for respiration. It acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP, the energy currency of cells. Without respiration, organisms would not be able to generate the energy needed for their survival and various cellular processes.

Respiration is an important process. Discuss respiration and explain its importance to an organism. In your answer, be sure to: • identify a gas produced by this process [1]

Correct Answer
co2
carbon dioxide
CO2

Explanation
Respiration is a vital process for organisms as it enables the conversion of glucose into energy. During respiration, carbon dioxide (CO2) is produced as a waste product. This gas plays a crucial role in maintaining the balance of gases in the atmosphere. It is essential for photosynthesis in plants, as they use CO2 to produce oxygen. Additionally, CO2 helps regulate the pH levels in the blood and is involved in maintaining the respiratory rate. Therefore, CO2, or carbon dioxide, is an important gas produced during respiration with various functions in the environment and within an organism.

Correct Answer
B. 2

Explanation
Cellular respiration is the process by which cells convert energy in food into a more usable form, specifically ATP. This process occurs in both animal and plant cells. It involves the breakdown of glucose and other organic molecules in the presence of oxygen, producing carbon dioxide and water as byproducts. Therefore, option 2 accurately describes cellular respiration.

Identify one physical or biological process taking place within a river, other than temperature change, that would affect the level of dissolved oxygen.

Correct Answer
cellular respiration
photosynthesis
respiration

Explanation
Cellular respiration, photosynthesis, and respiration are all processes that can affect the level of dissolved oxygen in a river. Cellular respiration is the process by which cells break down organic molecules to release energy, and this process can consume oxygen and decrease its level in the water. Photosynthesis, on the other hand, is the process by which plants and algae use sunlight to convert carbon dioxide and water into oxygen and glucose. This process can increase the level of dissolved oxygen in the river. Respiration refers to the exchange of gases between an organism and its environment, and it can either consume or release oxygen depending on the organism and the conditions.

Correct Answer
B. 2

Explanation
The correct answer is (2) releasing the stored energy of organic compounds by the process of respiration. Respiration is the process by which cells break down organic compounds, such as glucose, to release energy in the form of ATP molecules. This energy is then used by cells to perform various functions and activities. The other options, such as recycling light energy in photosynthesis, breaking down starch in digestion, and copying coded information in protein synthesis, are not directly related to the production of ATP molecules.

Name the process represented by the equation below. [1] glucose + oxygen --> carbon dioxide + water + ATP

Correct Answer
cellular respiration
respiration

Explanation
The equation provided represents the process of cellular respiration. This is a metabolic process in which glucose and oxygen are used to produce carbon dioxide, water, and ATP (adenosine triphosphate). Cellular respiration occurs in the cells of living organisms and is responsible for converting the energy stored in glucose into a usable form of energy (ATP) for the cell's activities. Respiration, on the other hand, is a broader term that can refer to both cellular respiration and other processes involved in gas exchange, such as breathing.

Correct Answer
ATP

Explanation
The given chemical equation represents cellular respiration, where glucose and oxygen are converted into carbon dioxide, water, and ATP (Adenosine Triphosphate). ATP is a molecule that stores and provides energy for cellular processes. It is often referred to as the "energy currency" of the cell because it is used to fuel various metabolic reactions. In this equation, X represents ATP, which is produced as a result of the breakdown of glucose during cellular respiration.
