Flashcard Photosynthesis, Cellular Respiration + Fossil Fuels Fall24

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, primarily composed of carbon and hydrogen, and used as energy sources.

Front

How are fossil fuels formed?

Back

Fossil fuels are formed from the heat and pressure acting on once-living aquatic organisms buried under layers of sediment over millions of years.

Front

Why are fossil fuels considered nonrenewable resources?

Back

Fossil fuels are considered nonrenewable because they take millions of years to form and cannot be replenished within a human timescale.

Front

What is the primary reactant that decreases during photosynthesis?

Back

The primary reactant that decreases during photosynthesis is carbon dioxide (CO2).

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: light + carbon dioxide + water → glucose + oxygen.

Front

What is a negative effect of using coal as a fossil fuel?

Back

A negative effect of using coal is that it releases a large amount of carbon dioxide, contributing to climate change.

Front

What is the role of water in photosynthesis?

Back

Water (H2O) is a reactant in photosynthesis, providing electrons and protons needed to convert carbon dioxide into glucose.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the equation for cellular respiration?

Back

The equation for cellular respiration is: glucose + oxygen → carbon dioxide + water + energy (ATP).

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).
