AQA A-Level Biology 3.5 Energy transfers in and between organisms quiz

On the thylakoid membranes of the chloroplast

In the fluid stroma of the chloroplast surrounding the thylakoids

On the inner mitochondrial membrane within the cell's mitochondria

In the general cytoplasm of the cell outside any organelle

The reduction of carbon dioxide

The photolysis of water

The breakdown of glucose

The oxidation of reduced NADP

Oxygen and water

Reduced NAD and reduced FAD

ATP and reduced NADP

Carbon dioxide and RuBP

Link reaction, glycolysis, Krebs cycle, oxidative phosphorylation

Glycolysis, Krebs cycle, link reaction, oxidative phosphorylation

Oxidative phosphorylation, glycolysis, link reaction, Krebs cycle

Glycolysis, link reaction, Krebs cycle, oxidative phosphorylation

It is the final electron acceptor, forming water

It is split by photolysis to provide the electrons that pass along the chain

It directly produces ATP without any involvement of the ATP synthase enzyme

It reduces NAD to reduced NAD so that the coenzyme can carry hydrogen

Ethanol and carbon dioxide

Lactate

Acetyl coenzyme A

Carbon dioxide and water

Substrate-level phosphorylation acting entirely on its own without any electron transport chain

The active transport of fully formed ATP molecules directly across the organelle membrane

Chemiosmosis, with protons flowing through ATP synthase

The direct transfer of a phosphate group straight from a glucose molecule onto ADP

Heat energy lost to the surroundings during respiration at each level

Energy lost in the faeces of the organism through the process of egestion

Energy lost from the organism in the form of various excretory products

Energy destroyed when glucose is broken down

8 percent

12.5 percent

2 percent

80 percent

The total amount of energy fixed by the plant during photosynthesis before any losses

Gross primary production minus respiratory losses

The total energy lost by the plant as heat during the process of respiration alone

The energy ingested by the primary consumers when they eat and digest the plant material

Denitrifying bacteria, in anaerobic conditions

Nitrogen-fixing bacteria, in root nodules

Nitrifying bacteria, in aerobic conditions

Saprobionts, in waterlogged soil

Algal bloom forms, fish gain extra oxygen, submerged plants grow faster, and the fish then thrive

Nitrate in the water poisons and kills the fish directly, and only afterwards do the algae grow

Decomposers add oxygen to the water, the algae die back, and the submerged plants grow strongly

Algal bloom blocks light, plants die, decomposers deplete oxygen, fish die
