Which of these is a characteristic of body cells that require large amounts of energy?(1 point) Responses They have a supplementary Y chromosome. They have a supplementary Y chromosome. They have a storage area for albumin proteins. They have a storage area for albumin proteins. They have a two-layer membrane. They have a two-layer membrane. They have a large number of mitochondria.

They have a large number of mitochondria.

The characteristic of body cells that require large amounts of energy is that they have a large number of mitochondria.

The characteristic of body cells that require large amounts of energy is that they have a large number of mitochondria.

To arrive at this answer, we need to understand what mitochondria are and their role in energy production within cells. Mitochondria are known as the powerhouses of the cell as they are responsible for generating energy in the form of ATP (adenosine triphosphate). More mitochondria in a cell mean higher energy production capacity.

To answer this question, we can eliminate the other options since they are not related to the energy requirements of cells.

- Having a supplementary Y chromosome does not directly affect the energy requirements of cells.
- Having a storage area for albumin proteins is unrelated to energy production; it is involved in protein storage and transport.
- Having a two-layer membrane is a general characteristic of many cell types and does not specifically indicate high energy requirements.

Therefore, the correct answer is that cells requiring large amounts of energy have a large number of mitochondria.

The diagram above represents two cells, X and Y. Which statement is correct concerning Cell X? (1 point) Responses It is a plant cell. It is a plant cell. It does not have a nucleus. It does not have a nucleus. It has an organelle that undergoes photosynthesis. It has an organelle that undergoes photosynthesis. It obtains its energy through cellular respiration in the mitochondria

The statement "It obtains its energy through cellular respiration in the mitochondria" is correct concerning Cell X.

This is because cellular respiration is the process by which cells convert glucose and oxygen into ATP, the main source of energy for cellular activities. Mitochondria are the organelles responsible for carrying out cellular respiration. Therefore, if Cell X obtains its energy through cellular respiration in the mitochondria, it means that it has mitochondria and is carrying out this energy-producing process.

6 C6H12O6 + 6 O2 → 6 H2O + 6 CO2 + ATP 6 C 6 H 12 O 6 + 6 O 2 → 6 H 2 O + 6 CO 2 + ATP 6 CO2 + 6 H2O + light → 6 O2 + 6 C6H12O6 6 CO 2 + 6 H 2 O + light → 6 O 2 + 6 C 6 H 12 O 6 6 CO2 + 6 ADP + light → 6 O2 + 6 H2O 6 CO 2 + 6 ADP + light → 6 O 2 + 6 H 2 O 6 CO2 + 6 H2O → 6 O2 + 6 ATP 6 CO 2 + 6 H 2 O → 6 O 2 + 6 ATP

The equation 6 CO2 + 6 H2O + light → 6 O2 + 6 C6H12O6 represents the process of photosynthesis.

This equation shows that with the help of light energy, carbon dioxide (CO2) and water (H2O) are converted into oxygen (O2) and glucose (C6H12O6). ATP (Adenosine Triphosphate) is not directly involved in photosynthesis. It is a molecule that is produced during cellular respiration, which occurs in the mitochondria.

Therefore, the correct equation for cellular respiration is 6 O2 + 6 C6H12O6 → 6 CO2 + 6 H2O + ATP.

Which of the cells characterized in the chart above is a plant cell? (1 point) Responses B B A A D D C C

Based on the given chart, cell A is a plant cell.

This can be determined by identifying the presence of characteristics specific to plant cells. Some of these characteristics include the presence of a cell wall and chloroplasts, which are responsible for photosynthesis. From the given options, only cell A is described to have an organelle that undergoes photosynthesis. Therefore, cell A is likely a plant cell.
