Which statement correctly describes how energy is made in photovoltaic cells and how energy is made in photosynthesis?(1 point)

Responses

Photovoltaic cells can make energy that needs light and energy that does not need light, while photosynthesis can only make energy that does not need light.
Photovoltaic cells can make energy that needs light and energy that does not need light, while photosynthesis can only make energy that does not need light.

Photovoltaic cells and photosynthesis can make energy that needs light and energy that does not need light.

The correct statement is:

Photovoltaic cells need light to make energy, while photosynthesis can make energy that needs light and energy that does not need light.

Photovoltaic cells convert sunlight into electrical energy (which requires light), while photosynthesis uses light energy to produce glucose and oxygen, and the energy stored in glucose can be utilized later in processes that do not directly require light.

Mitochondria are described as(1 point)
Responses

the storage centers of the cell.
the storage centers of the cell.

the powerhouses of the cell.
the powerhouses of the cell.

the production lines of the cell.
the production lines of the cell.

the energy currency of the cell.

The correct response is:

the powerhouses of the cell.

Mitochondria are known as the powerhouses of the cell because they are responsible for producing adenosine triphosphate (ATP), which is the main energy currency of the cell.

Which term best describes the reaction that makes pyruvic acid during cellular respiration?(1 point)
Responses

digestive reaction
digestive reaction

exothermic reaction
exothermic reaction

physical reaction
physical reaction

endothermic reaction

The best term to describe the reaction that makes pyruvic acid during cellular respiration is:

exothermic reaction.

The conversion of glucose to pyruvic acid during glycolysis releases energy, making it an exothermic reaction.

What is the definition of thermogenesis?(1 point)
Responses

living organisms make heat through metabolic activity
living organisms make heat through metabolic activity - no response given

living organisms make heat by lying in the sun
living organisms make heat by lying in the sun - no response given

living organisms make energy through metabolic activity
living organisms make energy through metabolic activity - incorrect

living organisms make energy through muscle contractions

The correct definition of thermogenesis is:

living organisms make heat through metabolic activity.

Thermogenesis refers to the process by which heat is produced in organisms, primarily through metabolic processes.

Which option is an electron carrier?(1 point)
Responses

ADP
ADP

ATP
ATP

NAD+
NAD+

FADH2

The correct option that is an electron carrier is:

NAD+.

NAD+ (nicotinamide adenine dinucleotide) serves as an electron carrier in various metabolic processes, including cellular respiration, where it helps transport electrons during oxidation-reduction reactions. FADH2 is also an electron carrier, but since only one option is requested, NAD+ is the most commonly recognized electron carrier form.

A protist that you observed in lab gains nutrients by absorbing small, liquid droplets. Which term best describes this metabolic process?(1 point)
Responses

pinocytosis
pinocytosis

photosynthesis
photosynthesis

phagocytosis
phagocytosis

decomposition

The term that best describes the metabolic process by which a protist absorbs small, liquid droplets to gain nutrients is:

pinocytosis.

Pinocytosis is a type of endocytosis where cells take in liquid and small solutes, effectively "drinking" them.
