The correct answer is A) phosphoenolpyruvate carboxylase; malic enzyme

In C4 plants, phosphoenolpyruvate carboxylase is found in the mesophyll cells to capture CO2, while malic enzyme is found in the bundle sheath cells to release CO2.

C4 plants have a specialized carbon fixation pathway that allows them to efficiently capture and concentrate CO2 in order to minimize photorespiration. In this pathway, the initial capture of CO2 occurs in the mesophyll cells, where phosphoenolpyruvate carboxylase (PEP carboxylase) is present. PEP carboxylase fixes CO2 to phosphoenolpyruvate (PEP), forming a four-carbon compound called oxaloacetate. This compound is then converted to malate, which is transported to the bundle sheath cells.

In the bundle sheath cells, malate is decarboxylated by malic enzyme, releasing CO2. This CO2 can then enter the Calvin cycle, where it is used in the synthesis of carbohydrates. The spatial separation of these processes in C4 plants allows for efficient CO2 concentration and reduced photorespiration.

Internal fertilization is essential for true terrestrial living because it provides a more secure and controlled environment for the fertilized egg and developing embryo.

In contrast, external fertilization, which occurs in aquatic environments, leaves the fertilized egg and developing embryo exposed to the risks of predation, dehydration, and changes in temperature, pH, and salinity.

In terrestrial environments, the risk of desiccation is particularly high, which makes the protection and retention of water a critical factor for the survival of the developing embryo.

Internal fertilization allows for the deposition of sperm directly into the female reproductive tract, where the egg is protected by a variety of mechanisms such as mucus, secretions, and physical barriers.

These protective measures help to ensure that the egg remains hydrated and is not subject to external stresses.

Furthermore, internal fertilization can also facilitate parental care, which is essential for the survival of offspring in many terrestrial species.

By providing a more secure environment for fertilization and development, internal fertilization allows for the evolution of a variety of reproductive strategies, such as the formation of eggs with hard shells, gestation within the female reproductive tract, and the production of yolk-rich eggs that provide nutrients for the developing embryo.

The regulatory mechanism in the citrate cycle involving the NADH-to-NAD+ ratio is considered to be an example of regulation by feedback inhibition or negative feedback.

In the citrate cycle, NAD+ (nicotinamide adenine dinucleotide) and NADH (reduced form of NAD+) are important coenzymes involved in redox reactions. The conversion of NAD+ to NADH and vice versa is a crucial step in the citrate cycle, and it is catalyzed by enzymes such as isocitrate dehydrogenase and alpha-ketoglutarate dehydrogenase.

When the concentration of NADH is high relative to NAD+, it signals that the energy status of the cell is high, indicating that the cell has sufficient energy reserves. In this case, the NADH molecules act as allosteric inhibitors and bind to specific regulatory sites on enzymes in the citrate cycle, such as isocitrate dehydrogenase. This binding inhibits the activity of the enzyme, slowing down the citrate cycle and reducing the production of NADH.

On the other hand, when the NADH-to-NAD+ ratio is low, it indicates a need for more energy production. In this case, NAD+ molecules act as activators, binding to the regulatory sites on enzymes and stimulating their activity. This promotes the citrate cycle and increases the production of NADH.

This regulatory mechanism ensures that the citrate cycle operates in a balanced manner, responding to the energy needs of the cell. It helps maintain homeostasis by inhibiting the cycle when energy reserves are high and stimulating it when energy is required. This feedback inhibition by NADH and NAD+ allows for efficient energy production and utilization in the cell.
