Photosynthesis Overview

An exothermic reaction in cells

Sum of all chemical reactions in a cell

Large molecules in food

Depends on mitochondria number

Cell organelles for energy production

Macromolecules from food

Increases heart rate

Measure of heart's beating speed

Respiration that uses oxygen.

Respiration that doesn't use oxygen.

Glucose is converted into energy, used by the body.

Transfers energy from nutrients to a usable form for living things.

Broken down, and excreted (passed out of the body).

Glycerol and fatty acids combine to form lipids.

Occurs when oxygen is low, like during intense exercise.

A process that breaks down nutrients to produce energy for cells.

Glucose + No Oxygen → Lactic Acid + Energy

C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy

Organisms need energy for cell repair, movement, and growth.

A process where glucose is broken down into alcohol and carbon dioxide, releasing energy.

Anaerobic respiration produces less energy than aerobic respiration because glucose is only partially broken down.

Exercise increases breathing rate and breath volume to deliver more oxygen to muscles and remove carbon dioxide.

The chemical equation representing the process of photosynthesis, combining carbon dioxide and water using light energy to produce glucose and oxygen.

Chlorophyll, a green pigment in plants, absorbs light energy for photosynthesis, converting it into chemical energy stored in glucose.

The rate of photosynthesis increases with increasing light intensity until it reaches a maximum point, where it levels off due to other limiting factors.

The rate of photosynthesis increases with temperature up to a certain point, after which it decreases rapidly due to enzyme denaturation.

Plants with reduced chlorophyll levels, due to diseases or mineral deficiencies, will have lower rates of photosynthesis.

Respiration is crucial for organisms as it releases energy stored in food, allowing for cellular processes and survival.

During respiration, carbon dioxide is released as a byproduct, which is then removed from the body.

As temperature increases, the rate of photosynthesis increases until a certain point, then decreases because the enzymes denature.

Increasing light intensity increases the rate of photosynthesis until another factor becomes limiting.

Increased carbon dioxide concentration increases the rate of photosynthesis.

Count the number of bubbles released in a given time (e.g., per minute) to measure the rate of photosynthesis.

Glucose produced in photosynthesis can be used for respiration, the process that releases energy from food.

Glucose can be converted into insoluble starch for storage, providing the plant with energy reserves.

Glucose can be used to produce fat or oil for storage, or cellulose, which strengthens the cell wall.

Photosynthesis is an endothermic reaction, meaning it absorbs energy from the environment.

Enzymes are biological catalysts that speed up the breakdown of glucose during respiration, releasing energy for the cell's activities.

Glucose + Oxygen → Carbon Dioxide + Water

Your heart rate increases to deliver more oxygenated blood to your muscles, providing them with the energy needed for contraction.

Glucose → Lactic Acid

Respiration provides energy for muscle contraction by breaking down glucose, which is essential for the movement of muscle fibers.

Respiration provides the energy that enzymes need to carry out their job of breaking down molecules and facilitating chemical reactions.
