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.
Which of the following is the equation for photosynthesis?(1 point)
Responses

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

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

6 CO2 + 6 H2O + light → 6 O2 + 6 C6H12O6
6 CO2 + 6 H2O + light → 6 O2 + 6 C6H12O6

The correct characteristic of body cells that require large amounts of energy is:
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. Mitochondria are the cellular organelles responsible for generating energy in the form of ATP (adenosine triphosphate), which is used as a fuel source for various cellular processes.
To determine which of the given options is the correct answer, we can analyze each option and eliminate those that are not related to cellular energy production:
1. They have a supplementary Y chromosome - This option is not related to cellular energy production and can be eliminated.
2. They have a storage area for albumin proteins - Although proteins are involved in many cellular processes, this option does not specifically correlate with high energy demands in cells. We can eliminate this option as well.
3. They have a two-layer membrane - While cellular membranes are important for various cellular functions, the number of layers in the membrane is not directly related to energy requirements. We can eliminate this option.
4. They have a large number of mitochondria - This option directly correlates with energy production in cells. Mitochondria are known as the "powerhouses" of cells due to their role in generating ATP through cellular respiration. This option is the correct answer.
In conclusion, the characteristic of body cells that require large amounts of energy is that they have a large number of mitochondria.
