The Alternative Pathways of Photosynthesis Using the C4 or CAM

question 2

Multiple Choice

The alternative pathways of photosynthesis using the C4 or CAM systems are said to be compromises. Why?

• A) Each one minimizes both water loss and rate of photosynthesis.
• B) C4 compromises on water loss and CAM compromises on photorespiration.
• C) Both minimize photorespiration but expend more ATP during carbon fixation.
• D) CAM plants allow more water loss, whereas C4 plants allow less CO2 into the plant.
• E) C4 plants allow less water loss but CAM plants allow more water loss.

Definitions:

High-impedance Load

An electrical load that presents a high resistance to current flow, requiring minimal power from the source.

I/O Leakage

Unintended current that flows through the input/output circuitry of a device, even in its off state, potentially causing erroneous readings or operations.

Solid-state Switching

Solid-state Switching involves the use of semiconductor devices to control the flow of electricity without moving parts, offering advantages in durability and response time.

Grounding Requirements

refer to the essential criteria for establishing electrical connections to the earth to ensure safety and prevent electrostatic discharge.
